Namur Valve

Overview

NAMUR is an acronym for the User Association of Automation Technology in Process Industries and defines a standardized interface for automated valve technology. NAMUR valves are designed to be directly mounted onto pneumatic actuators, simplifying installation and reducing overall system costs.

NAMUR Standard & Interface (As Provided)

The NAMUR standard specifies uniform mounting interfaces for solenoid valves and pneumatic actuators. This standardization allows solenoid valves to be mounted directly to the actuator inlet and outlet ports without additional fittings, minimizing installation time and cost.

Operating Principle (As Provided)

A NAMUR solenoid valve controls media flow by using an electrically operated solenoid to regulate compressed air supplied to a pneumatic actuator. The actuator converts compressed air energy into mechanical motion, opening or closing the valve as required.

Solenoid & Actuator Interaction (As Provided)

The solenoid valve and pneumatic actuator work together to control flow direction, flow rate, and operating speed. Depending on system design, the valve may operate in either a normally closed or normally open configuration.

Solenoid Valve Configurations (As Provided)

• 3-way solenoid valves with one inlet, one outlet, and one exhaust port
• Two-seat design for basic pneumatic control
• 4-way solenoid valves with multiple inlets and exhaust ports
• Commonly used with double-acting rack and pinion actuators

Applications (As Provided)

• Automated on/off valve control systems
• Pneumatic actuator-driven process valves
• Industrial automation and process control
• Flow direction and flow speed regulation systems

Operational Benefits (As Provided)

• Direct mounting to pneumatic actuators
• Reduced installation and maintenance costs
• Compact and standardized design
• Reliable control of flow direction and operation
• Seamless integration with automation systems
