Hafner - Namur Flow Control Valves

Hafner - Namur Flow Control Valves

A NAMUR valve is a pneumatic valve with a special connection pattern for the valve’s outlets. These outlets are normally ports 2 and 4 of a valve. This type of connection allows the valves to be mounted directly on a pneumatic actuator that is equipped with the same NAMUR standard. A pneumatic actuator is responsible for opening and closing, for example, ball valves and butterfly valves.

Thanks to this NAMUR standard, you can mount the valve directly on the actuator. Hoses and fittings between the valve and the actuator are therefore not necessary.
