  • Kv Value: This is the flow coefficient, measured in cubic meters per hour. It indicates the flow rate through the valve and is critical for determining the valve’s suitability for your application.
  • Pressure Range: The pressure range of the application must be matched with the valve’s specifications to ensure proper operation (Bürkert).

NAMUR Standard Interfaces

NAMUR, an acronym for the User Association of Automation Technology in Process Industries, sets standards for automated valve technology. Standard interfaces, such as NAMUR, are beneficial for actuator mountings because they streamline manufacturing and installation processes, reducing costs (Bürkert).

Using NAMUR standard interfaces can offer several advantages:

  • Compatibility: Ensures that the valve can be easily integrated with various actuators and control systems.
  • Cost-Effectiveness: Simplifies installation and reduces the need for custom fittings.
  • Reliability: Provides a standardized approach, ensuring consistent performance across different applications.
