Pneumission has developed a valve with Namur interface.
For many years Pneumission produces high quality Namur valves for their international customer with many options such as stainless steel components or HNBR seals.
5/2 valves are for double acting actuators.
For a spring retour actuator you only need a 3/2 valve.
Now Pneumission manufactures a 3 way valve with the same dimensions as the 5/2 valve so it can be used on the Namur interface of the actuator.
Namur solenoid valve are for controlling the direction of pneumatic rotary actuators.
