Understanding Solenoid Valves

Basics of Solenoids

A solenoid is an electromechanical device that converts electrical energy into mechanical motion. It operates based on the principles of electromagnetism. When an electric current passes through the solenoid wire, it generates a magnetic field. This magnetic field attracts a piece of metal wrapped inside the wire, causing it to move towards one end of the solenoid. However, this effect is temporary. Once the electrical current is cut off, the magnetic field disappears, and the metal piece, due to spring-loading, reverts back to its original position (HowStuffWorks).

Applications of Solenoid Valves

Solenoid valves are versatile and widely used in various industries to control the flow of liquids or gases. Here are some common applications:

  • Industrial Machinery: Solenoid valves are used to control machines, dose, mix, or restrict the flow of liquids or gases. For example, they are crucial in beverage factories to measure the exact amount of drink to be poured into bottles (Starter Solenoid).
  • Agriculture: Solenoid valves are essential in agricultural equipment, such as irrigation devices. These valves control the flow of water in automatic sprinklers or motorized farm machines, ensuring precise dosing of substances. An irrigation solenoid valve, for instance, can autonomously operate a sprinkler’s function (Starter Solenoid).
  • Refrigeration Systems: In refrigeration, solenoid valves prevent high-pressure compressor starts, protect the compressor from fluid hammer issues, and regulate the passage of refrigerant as required.
  • General Industrial Use: Solenoid valves are electromechanical devices used to control the flow of fluids or gases in various industrial applications. They consist of an electromagnetic coil that, when activated, moves a plunger to open and close internal valves, allowing for precise regulation of pressure, speed, and volume of the fluid passing through (Valves Actuator).

Understanding the basics and applications of solenoid valves can help you make informed decisions for your agricultural needs, ensuring efficient and effective crop spraying. For more information on solenoid valves, explore our detailed guide on solenoid valves.

Types of Solenoid Valves

When choosing solenoid valves for your crop spraying system, it’s essential to understand the different types available. This knowledge helps you select the best valve suited for your needs, improving efficiency and reliability.

Direct-acting vs. Pilot-operated Valves

Direct-acting solenoid valves are designed to directly actuate the main valve. These valves convert electrical energy into mechanical energy to obstruct or allow fluid flow. They are best used when the force required is low enough. However, they require a significant amount of power relative to other solenoid types.

Pilot-operated solenoid valves, on the other hand, are ideal for applications with high fluid pressures and large orifice diameters. These valves use the pressurized fluid itself to apply the necessary forces to actuate the valve. The solenoid directs the fluid, making these valves more energy-efficient than direct-acting valves. However, they require sufficient fluid pressure to function and are more prone to clogging if the fluid contains solid impurities (Wikipedia).

Valve TypePower ConsumptionSuitable for High PressureSusceptibility to Clogging
Direct-actingHighNoLow
Pilot-operatedLowYesHigh

Normally Open vs. Normally Closed Valves

Solenoid valves can also be categorized as normally open (NO) or normally closed (NC). This classification is based on the valve’s state when it is de-energized.

A normally closed solenoid valve remains closed in its de-energized state. When current flows through the solenoid, the coil is energized, creating a magnetic field that moves the plunger to open the orifice and allow fluid flow. These valves are ideal for applications that require the valve to be closed for long periods, as they are more energy-efficient. They are also often used for safety reasons, such as in gas appliances (Tameson).

A normally open solenoid valve, conversely, remains open when de-energized. When the solenoid is energized, the plunger moves to close the orifice, stopping the fluid flow. This type is suitable for applications where the valve needs to remain open for extended periods.

Valve TypeState When De-energizedEnergy EfficiencyCommon Applications
Normally ClosedClosedHighLong-term closure, safety
Normally OpenOpenLowLong-term opening, continuous flow

Understanding these distinctions will help you determine what triggers a solenoid valve in your specific crop spraying setup. For more information on solenoid valves, visit our detailed guide on solenoid valves.

How Solenoid Valves Work

Understanding how solenoid valves function can help you make better decisions about selecting and maintaining them for your crop spraying needs. This section explains the electromagnetic principle and the actual functioning of solenoid valves.

Electromagnetic Principle

Solenoid valves operate based on the principles of electromagnetism. When an electric current runs through a coil, it creates a magnetic field. This magnetic field then attracts a movable core, known as an armature or plunger. The movement of this plunger is what opens or closes the valve, converting electrical energy into mechanical motion and force (Electric Solenoid Valves).

Here’s how it works:

  1. Current Flow: An electric current flows through the coil.
  2. Magnetic Field: The coil generates a magnetic field.
  3. Plunger Movement: The magnetic field attracts the plunger, causing it to move.
  4. Valve Action: The movement of the plunger either opens or closes the internal valve.

Functioning of Solenoid Valves

Solenoid valves can be categorized as normally open or normally closed. In a normally closed valve, the valve remains closed when it is de-energized. When current flows through the solenoid, the coil is energized, creating a magnetic field that moves the plunger to open the valve and allow the flow of media through it (Tameson).

StateActionMagnetic FieldPlunger PositionValve Status
De-energizedNo currentNoneClosedClosed
EnergizedCurrent flowsPresentOpenOpen

In the energized (open) state, the current flowing through the coil creates a magnetic field that moves the plunger, causing the internal valves to open and allowing fluid or gas to flow through. In the de-energized (closed) state, no current runs through the coil, resulting in the internal valves remaining closed and blocking the flow of fluid or gas (Valves Actuator).

Solenoid valves offer a quick response time, with the plunger able to move from open to close in as little as 0.1 milliseconds. This enables precise and efficient control over fluid flow, making them suitable for various applications that require rapid response times (Valves Actuator).

Factors Influencing Solenoid Valve Performance

Several factors can influence the performance of solenoid valves, particularly in agricultural applications like crop spraying. Understanding these elements can help you optimize your equipment for better efficiency and reliability.

Coil Strength and Current

The strength of a solenoid valve is determined by the number of coils in the wire and the current sent through it. According to Ampere’s law, these factors govern the strength of the electromagnetic field generated by the solenoid. The electromagnetic field’s strength directly impacts the valve’s ability to open and close effectively.

FactorDescriptionImpact
Number of CoilsMore coils increase the magnetic field strengthStronger actuation force
CurrentHigher current increases the magnetic field strengthFaster response time

Ensuring the coil strength and current are appropriately matched to your solenoid valve’s specifications is crucial for maintaining optimal performance. For more detailed information, you can refer to our article on what triggers a solenoid valve.

Response Time and Customization

Solenoid valves are known for their quick response time, with the plunger able to move from open to close in as little as 0.1 milliseconds. This rapid response is essential for applications that require precise and efficient control over fluid flow, such as crop spraying.

Customization options are available to enhance the performance of solenoid valves. These options may include different materials for the valve body and seals, varying coil voltages, and specialized coatings to improve durability and resistance to chemicals used in agriculture.

For more detailed comparisons, you can explore our sections on what is the difference between a 2-way and 3 way solenoid valve.

Operational Aspects of 3-Way Valves

Response Time and Differential Pressure

For a 3 way solenoid valve, the response time is the duration required for the valve to transition from an open to a closed position, or vice versa. This is crucial, especially in applications like crop spraying where timely operation can impact the effectiveness of the process. The response time can vary based on several factors, including the valve’s design, the characteristics of the coil, air pressure, and the viscosity of the fluid being controlled. Direct-operated valves generally respond faster than indirect ones.

Type of ValveResponse Time (ms)
Direct-Operated20 – 40
Indirect-Operated40 – 60
DC Valves30 – 50
AC Valves20 – 40

Differential pressure is another important aspect to consider. It refers to the difference in pressure between the inlet and outlet of the valve. For crop spraying, maintaining the right differential pressure ensures that the fluid is dispensed evenly and effectively. Using the appropriate valve helps in managing this aspect efficiently.

Direct vs. Indirect Operation

When selecting a 3 way solenoid valve, understanding the difference between direct and indirect operation is vital. Direct-operated valves, also known as direct-acting valves, utilize a solenoid coil that directly moves the valve’s mechanism to open or close it. These valves are faster and more reliable for applications requiring quick response times.

Indirect-operated valves, on the other hand, rely on the system’s pressure to assist in opening and closing the valve. While they may have slightly slower response times, indirect valves are suitable for applications where higher flow rates are needed and where the system pressure can aid in the valve operation.

Operation TypeAdvantagesDisadvantages
Direct-OperatedFaster response time, Simple designLimited by pressure and flow rate
Indirect-OperatedHandles higher flow rates, Utilizes system pressureSlower response time, More complex design

Understanding these operational aspects helps you make an informed decision when choosing the best 3 way solenoid valve for your crop spraying needs. For more detailed information, check out our article on what is the difference between a 2-way and 3 way solenoid valve.

Functional Types of 3-Way Valves

A 3-way solenoid valve features three ports: an orifice, a cavity, and a stop port, used for directional control (IQS Directory). These valves can be categorized into three functional types:

  1. Normally-Closed (NC): In this configuration, the valve remains closed when de-energized, blocking flow from the inlet to the outlet. When energized, the valve opens, allowing fluid to flow through.
  2. Normally-Open (NO): This type operates oppositely. It remains open when de-energized, allowing fluid to flow. When energized, it closes, stopping flow.
  3. Universal: This versatile type can function as either normally-closed or normally-open, depending on the specific needs of your application.

Components of a 3-Way Solenoid Valve

A 3-way solenoid valve consists of several key components that work together to control the flow of fluids or gases:

  1. Inlet Port: This is where the fluid or gas enters the valve.
  2. Outlet Port: The fluid exits through this port.
  3. Exhaust Port: This port allows the fluid or gas to be expelled from the system.
  4. Solenoid Coil: When energized, this coil creates a magnetic field that moves the plunger.
  5. Plunger: The plunger moves up and down within the valve to open or close the flow paths.
  6. Spring: This component returns the plunger to its original position when the solenoid is de-energized.
  7. Valve Body: Constructed from materials such as bronze, aluminum, steel, or plastic, the body houses all the internal components and directs the flow of fluid (IQS Directory).

Here’s a table summarizing the components and their function:

Operation of 3-Way Solenoid Valves

Understanding how a 3-way solenoid valve operates can help you make informed decisions about your agricultural equipment, especially when it comes to crop spraying. These valves are designed to control the direction of media flow within a system.

Normally-Closed vs. Normally-Open Valves

A 3-way solenoid valve can be either normally-closed (NC) or normally-open (NO) when not energized. The main difference between these two types lies in the state of the valve when it is de-energized.

  • Normally-Closed (NC) Valve: In this configuration, the valve remains closed when not energized. The orifice is blocked, preventing any flow of media. When you apply electrical energy, the valve opens, allowing the media to flow through the system (IQS Directory). This type of valve is useful in applications where you need to stop the flow automatically when power is lost.
  • Normally-Open (NO) Valve: In contrast, a normally-open valve remains open when de-energized. The orifice allows the media to flow freely. When you energize the valve, it closes, stopping the flow of media. This configuration is beneficial in scenarios where you need the flow to continue in the absence of power (IQS Directory).
Type of ValveState When De-energizedState When Energized
Normally-Closed (NC)ClosedOpen
Normally-Open (NO)OpenClosed

The exhaust port in these valves provides pressure relief, enhances performance, and ensures system safety (Electric Solenoid Valves). For more information on the differences between 2-way and 3-way valves, you can visit our article on what is the difference between a 2-way and 3-way solenoid valve.

Pilot-Acting Solenoid Valves

Pilot-acting solenoid valves, also known as servo-assisted solenoids, control the flow based on the differential pressure across the valve ports. These valves are particularly known for their low power consumption, broad operating pressure ranges, and high flow capacities (IQS Directory).

The operation of a pilot-acting solenoid valve involves using a small solenoid to control a larger valve. When the solenoid is energized, it opens a pilot orifice, which causes a pressure differential. This differential moves the diaphragm or piston, allowing media to flow through the main valve.

FeatureBenefit
Low Power ConsumptionEnergy-efficient operation
Broad Operating Pressure RangesVersatile for different applications
High Flow CapacitiesEfficient media transfer

These valves are ideal for applications requiring precise control of media flow, such as in irrigation systems and crop spraying equipment. For additional advice on selecting the best solenoid valve for your needs, refer to our guide on 3 way solenoid valve.

Understanding Solenoid Valves

Before diving into what triggers a solenoid valve, it’s essential to grasp the basics and the different types of solenoid valves. This knowledge will help you make more informed decisions when considering their use in agricultural applications, particularly for crop spraying.

Solenoid Valve Basics

A solenoid valve is an electromechanical device used to control the flow of liquids or gases. It consists of a solenoid (a coil of wire that creates a magnetic field when an electric current passes through it) and a valve mechanism. When energized, the solenoid moves the valve to open or close the flow passage. Solenoid valves are widely used in various industries, including agriculture, to regulate the flow of water, chemicals, and other fluids.

Key Components:

  • Solenoid Coil: Generates a magnetic field when electric current flows through it.
  • Plunger: Moves within the coil, opening or closing the valve.
  • Spring: Helps return the plunger to its original position when de-energized.

Types of Solenoid Valves

Solenoid valves come in various designs, each tailored for specific applications. Understanding the types can help you select the best option for your crop spraying needs.

Two-Port Solenoid Valves

These valves have two ports—an inlet and an outlet—and are designed to regulate the flow of a single fluid. They are straightforward and commonly used in on/off applications.

Valve TypeDescription
Normally Open (N.O.)Allows flow when de-energized; stops flow when energized.
Normally Closed (N.C.)Stops flow when de-energized; allows flow when energized.

Three-Port Solenoid Valves

Three-port solenoid valves can direct flow between different pathways. These are ideal for more complex systems requiring multiple flow configurations.

Manifold Assemblies

Multiple solenoid valves can be mounted on a manifold, allowing for centralized control of several fluid pathways. This setup is especially useful in agricultural equipment where multiple spraying lines need to be controlled.

Port ConfigurationFunction
Three-PortSwitches flow between two outlet ports.
Four-PortCommon in pneumatic applications for controlling double-acting cylinders.

When exploring solenoid valves for crop spraying, consider the specific requirements of your application. For example, a direct-acting solenoid valve might be more suitable for controlling smaller fluid passages, while a pilot-operated valve could be better for larger systems.

By understanding these basics and types, you’ll be better equipped to choose the right solenoid valve for your agricultural needs. For more information on solenoid valves and their uses, check out our in-depth articles on solenoid valves.

Functionality of Solenoid Valves

Understanding the functionality of solenoid valves is crucial for optimizing their use in crop spraying. This section explores the differences between direct-acting and pilot-operated valves, as well as their power consumption and supply requirements.

Direct-Acting vs. Pilot-Operated Valves

Direct-acting solenoid valves convert electrical energy into mechanical energy. This action physically moves a barrier to either obstruct flow (normally open, N.O.) or allow flow (normally closed, N.C.). A spring often returns the valve to its resting position once power is shut off. These valves operate quickly, typically within 5 to 10 milliseconds.

Valve TypeOperation Time (ms)
Direct-Acting5 – 10
Pilot-Operated15 – 150

Pilot-operated solenoid valves, on the other hand, use the pressurized fluid itself to apply the forces required to actuate the valve. The solenoid acts as a “pilot,” directing the fluid. These valves are ideal for applications requiring large pressures and volumes, such as irrigation systems (Wikipedia).

Power Consumption and Supply Requirements

The power consumption and supply requirements of a solenoid valve are determined by factors such as fluid pressure and orifice diameter. For instance, a 3⁄4-inch 150 psi sprinkler valve designed for residential systems has a momentary inrush of 7.2 VA and a holding power requirement of 4.6 VA.

Valve SpecificationPower Consumption (VA)
Inrush7.2
Holding4.6

Proper installation is critical to avoid malfunctions. Solenoid valves should not be operated under vibrations exceeding 50 m/s², as it may cause malfunction. For more details on installation and maintenance, visit our section on installation tips for solenoid valves.

By understanding the functionality of direct-acting and pilot-operated valves, as well as their power requirements, you can make informed decisions that enhance the efficiency of your crop spraying operations.

Understanding Solenoid Valves

Solenoid Valve Basics

Solenoid valves are essential components in many agricultural applications, particularly in crop spraying. They convert electrical energy into mechanical energy, which triggers a magnetic response. This activation controls the flow of fluid in hydraulic and pneumatic systems (The Hope Group). Understanding how solenoid valves function is crucial for efficient crop spraying.

The basic components of a solenoid valve include:

  • Solenoid Coil: Generates a magnetic field when an electrical current passes through it.
  • Plunger: Moves within the valve to open or close the orifice.
  • Orifice: The opening through which the fluid flows.
  • Spring: Returns the plunger to its original position when the coil is de-energized.

The operation of a solenoid valve can be summarized as follows:

  1. In the de-energized state, the valve remains in its default position (either open or closed).
  2. When electrical current flows through the solenoid coil, it becomes energized and creates a magnetic field.
  3. The magnetic field moves the plunger, changing the position of the valve (either opening or closing the orifice).

Types of Solenoid Valves

There are several types of solenoid valves, each designed for specific applications and operating conditions. The main types include normally closed, normally open, and bi-stable (latching) solenoid valves.

Type of Solenoid ValveDescriptionIdeal ApplicationsEnergy Efficiency
Normally Closed (NC)In the de-energized state, the valve is closed. Energizing the coil opens the valve.Safety-critical applications, gas appliancesHigh when closed for long periods
Normally Open (NO)In the de-energized state, the valve is open. Energizing the coil closes the valve.Preventing overpressure, systems needing continuous flowHigh when open for long periods
Bi-Stable (Latching)The valve stays in its last switched position when de-energized.Systems requiring minimal power consumptionVery high due to low power usage

  • Normally Closed (NC) Solenoid Valves: These valves are closed in the de-energized state. When the coil is energized, the magnetic field moves the plunger to open the orifice, allowing fluid to flow through the valve. They are ideal for applications where the valve needs to stay closed for long periods, as they are energy-efficient and can be used for safety purposes (Tameson).
  • Normally Open (NO) Solenoid Valves: These valves are open in the de-energized state. When the coil is energized, the plunger moves to close the orifice, stopping the fluid flow. They are suitable for applications that require the valve to be open for extended periods, such as preventing overpressure situations (Tameson).
  • Bi-Stable (Latching) Solenoid Valves: These valves can be switched by a momentary power supply and remain in the switched position when de-energized. They use permanent magnets instead of a spring, resulting in reduced power consumption. This makes them suitable for systems that need to minimize power usage.

To learn more about the operation of these valves, check out our detailed guide on what triggers a solenoid valve. Understanding these different types will help you select the best solenoid valve for your crop spraying needs.

Operation of Solenoid Valves

Solenoid valves play a crucial role in various agricultural applications, especially in crop spraying systems. Understanding their operation can help you optimize their use and ensure efficient performance. Here, we explore the operation of two main types of solenoid valves: direct-acting solenoid valves and pilot-operated solenoid valves.

Direct-Acting Solenoid Valves

Direct-acting solenoid valves work by converting electrical energy into mechanical energy. This process physically moves a barrier to either obstruct or allow fluid flow, depending on the valve’s design. These valves are typically categorized as either normally open or normally closed.

In a direct-acting solenoid valve, the seat seal is attached directly to the solenoid core. When the valve is de-energized, the seat orifice remains closed. Energizing the valve opens the orifice, allowing fluid to pass through (Omega).

TypeOperation Time
Direct-Acting Solenoid Valve5 to 10 milliseconds

Direct-acting solenoid valves are known for their rapid response time, typically operating within 5 to 10 milliseconds (Wikipedia). These valves are ideal for applications requiring quick actuation, such as crop spraying.

Pilot-Operated Solenoid Valves

Pilot-operated solenoid valves utilize pressurized fluid to apply the necessary forces for actuation. The solenoid directs this fluid, allowing the valve to handle higher pressures and volumes. These valves are commonly used in high-pressure applications, such as dishwashers and irrigation systems.

Pilot-operated solenoid valves generally have a slower response time compared to direct-acting valves. Typical operation times range from 15 to 150 milliseconds (Wikipedia).

TypeOperation Time
Pilot-Operated Solenoid Valve15 to 150 milliseconds

These valves are particularly suitable for crop spraying systems, where the ability to handle large volumes and high pressures is essential.

Both direct-acting and pilot-operated solenoid valves have their specific applications and advantages. By understanding their operation, you can select the best type of solenoid valve for your agricultural needs.

Understanding Solenoid Valves

Basics of Solenoid Valves

A solenoid valve is an electromechanically operated valve widely used in various agricultural applications, including crop spraying. The primary function of a solenoid valve is to control the flow of liquids or gases. It works by having the media controlled by the valve enter through the inlet port, flow through the orifice, and then continue into the outlet port. The orifice is opened and closed by the plunger, which is lifted by an electromagnetic field created by the coil. This process allows the media to flow through the valve (Solenoid Valve Info).

ComponentFunction
Inlet PortEntry point for the media (liquid or gas)
Outlet PortExit point for the media
OrificePathway that opens or closes to allow or block the flow of media
PlungerMoves to open or close the orifice, controlled by the solenoid coil
Solenoid CoilGenerates an electromagnetic field to move the plunger

Components of a Solenoid Valve

To understand how solenoid valves work, it’s important to be familiar with their key components:

  • Solenoid Coil: The solenoid coil generates a magnetic field when the valve is energized. This magnetic field controls the mechanical parts of the valve that regulate flow (Electric Solenoid Valves). The coil is essentially a wire wound into a coil shape, and when an electric current passes through it, an electromagnetic field is produced.
  • Plunger: The plunger is a movable part within the solenoid valve that directly controls the opening and closing of the orifice. When the solenoid coil is energized, the electromagnetic field lifts the plunger, allowing the media to flow through the valve. When the coil is de-energized, the plunger returns to its original position, closing the orifice and stopping the flow. The position of the plunger determines whether the valve is normally closed or normally open.
  • Orifice: The orifice is the pathway through which the media flows. The size of the orifice can vary, affecting the flow rate. The plunger either opens or closes this pathway to regulate the flow.
  • Inlet and Outlet Ports: These are the entry and exit points for the media controlled by the valve. The inlet port allows the media to enter, while the outlet port allows it to exit once it has passed through the orifice.

Understanding these components and their functions can help you troubleshoot any issues and make informed decisions when selecting or replacing solenoid valves for your crop spraying needs. For more detailed information, check out our article on what triggers a solenoid valve.

Working Principles of Solenoid Valves

Magnetic Field Operation

To understand what triggers a solenoid valve, it’s important to grasp the basics of magnetic field operation. When the solenoid valve is energized, an electrical current flows through the solenoid coil, creating a magnetic field. This magnetic field is crucial in controlling the mechanical parts of the valve that regulate fluid flow (Electric Solenoid Valves).

The magnetic field generated by the solenoid coil attracts or repels a component known as the plunger. The movement of this plunger determines whether the orifice through which the fluid flows is open or closed. This process is fundamental in crop spraying systems where precise control of fluid flow is necessary for efficient operation.

Opening and Closing Mechanism

The opening and closing mechanism of a solenoid valve is straightforward yet highly effective. When the solenoid coil generates a magnetic field, it moves the plunger up or down. This movement either opens or closes the valve’s orifice, allowing or stopping fluid flow (Tameson).

Whether the solenoid valve is in a normally open or normally closed state determines how it operates. In a normally closed valve, the plunger blocks the orifice, preventing fluid flow until the solenoid is energized. Conversely, in a normally open valve, the orifice remains unblocked until the solenoid is energized, causing the plunger to close the orifice (Electric Solenoid Valves).

For those interested in how different types of solenoid valves work in agricultural settings, understanding these mechanisms is key. Proper comprehension of these principles will help you make informed decisions when selecting or replacing solenoid valves for your crop spraying systems.

Solenoid CoilGenerates magnetic field
PlungerMoves to open/close the orifice
OrificeControls fluid flow

By understanding these fundamental principles, you can better appreciate the role of solenoid valves in agriculture and how they improve the efficiency of crop spraying systems. For more detailed information, check out our articles on solenoid valves and what triggers a solenoid valve.

Types of Solenoid Valves

Understanding the different types of solenoid valves is essential for optimizing your crop spraying system. Solenoid valves are crucial in regulating fluid flow, and selecting the right type can enhance your farming efficiency. This section explores the primary types of solenoid valves: normally open, normally closed, and bi-stable or latching valves.

Normally Open vs. Normally Closed

Normally Open Solenoid Valves

Normally open solenoid valves are open when de-energized, allowing fluid to flow freely. When an electrical current is sent to the coil, it creates an electromagnetic field that forces the plunger downwards, closing the seal and preventing fluid flow (Tameson). This type of valve is ideal for applications where you want the default state to allow fluid flow, such as in certain irrigation systems.

FeatureNormally Open Solenoid Valve
Default StateOpen
When EnergizedCloses
Typical UseSystems needing default fluid flow

Normally Closed Solenoid Valves

Conversely, normally closed solenoid valves are closed when de-energized, preventing fluid flow. When current is sent to the coil, it creates an electromagnetic field that forces the plunger upwards, unseating the seal and allowing fluid flow (Tameson). This type of valve is commonly used in crop spraying systems where you want to control the flow of chemicals or water actively.

FeatureNormally Closed Solenoid Valve
Default StateClosed
When EnergizedOpens
Typical UseControlled fluid release

For a more in-depth understanding of what triggers a solenoid valve, you can visit our dedicated article on what triggers a solenoid valve.

Bi-Stable or Latching Valves

Bi-stable or latching solenoid valves are unique because they can be switched by a momentary power supply and remain in the position they switched to when de-energized. These valves use permanent magnets instead of a spring, thus reducing power consumption and making them highly energy-efficient (Tameson). This feature is particularly beneficial in remote agricultural applications where power availability may be limited.

FeatureBi-Stable or Latching Valve
Default StateDepends on last energized state
When EnergizedSwitches position
Energy EfficiencyHigh, due to momentary power usage

These valves are suitable for systems requiring a stable state without continuous power, such as in automated irrigation setups where you may need to switch between open and closed states infrequently.

By understanding the various types of solenoid valves, you can make informed decisions to improve your crop spraying efficiency. For more details on selecting the right solenoid valves, visit our comprehensive guide on solenoid valves.
