The SIL3 rated Namur solenoid directional control valves are actuator accessories used for the on/off control of single-acting or double-acting pneumatic actuators. By being directly coupled to pneumatic actuators and energizing the directional valve, these valves enable the actuator to change its position. Namur solenoid valves are available with single or double coils, and 3/2 or 5/2 port options.
