When choosing the right 3 way solenoid valve for your agricultural needs, it’s important to understand the different types and configurations available. This section covers the distinctions between direct-acting versus indirect-acting valves and normally-open versus normally-closed valves.
Direct-Acting vs. Indirect-Acting
Direct-Acting Solenoid Valves
Direct-acting solenoid valves operate without the need for external pressure. When energized, the electromagnetic field lifts the plunger directly, allowing fluid or gas to flow. This type of valve is ideal for low-flow applications and provides quick response times.
Indirect-Acting Solenoid Valves
Indirect-acting solenoid valves, also known as pilot-operated valves, use the system’s pressure to assist in valve operation. When energized, the pilot valve opens, allowing pressure to move the main valve. Indirect-acting valves are suitable for high-flow applications and can handle larger volumes of fluid or gas.

Normally-Open vs. Normally-Closed
Normally-Open (NO) Solenoid Valves
In a normally-open three-way solenoid valve, the default state allows fluid or gas to flow through the valve. When the valve is energized, the flow path is blocked. This type of valve is useful in applications where fluid flow is required in the default state and can be stopped when needed.
Normally-Closed (NC) Solenoid Valves
A normally-closed three-way solenoid valve blocks fluid or gas flow in its default state. When energized, the valve opens, allowing flow. This configuration is ideal for applications where fluid flow is only needed when the valve is activated.
By considering factors such as operating mechanism, default state, and application requirements, you can ensure efficient and reliable performance in your agricultural operations.

Selection and Considerations for Three-Way Solenoid Valves
Selecting the right 3 way solenoid valve for your crop spraying system involves understanding various factors and considerations that ensure optimal performance and longevity.
Factors for Choosing the Right Valve
When choosing a three-way solenoid valve, several factors need to be taken into account:
Type of Medium: Consider the type of fluid or gas the valve will control. Some materials are better suited for specific media to prevent corrosion and wear.
Working Principle: Determine if your application requires a direct-acting, semi-direct, or indirect-acting valve.
Voltage: Ensure the valve matches the voltage requirements of your system.
Environment: Consider the environmental conditions such as humidity, temperature, and exposure to chemicals.
Response Time: Select a valve with an appropriate response time for your application.
Pressure Range: Ensure the valve can handle the operating pressure of your system.
Temperature Range: Verify that the valve can operate within the temperature range of your application.
IP Rating: Check the Ingress Protection rating to ensure the valve can withstand environmental factors like dust and water.
Valve Size and Threading: Make sure the valve size and threading match your system’s specifications.
Stroke: Consider the stroke length of the valve.
Seal Material: Choose a seal material compatible with the medium to prevent leaks and wear.
Operating Time: Ensure the valve can handle the required operating time without overheating or failing.
Material, Pressure, and Temperature Considerations
The material of the solenoid valve is crucial for its durability and compatibility with the medium it controls. Solenoid valves can be constructed from various materials such as bronze, aluminum, steel, and plastic (IQS Directory). Here’s a table summarizing common materials and their properties:
