Ex-proof 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 have protection ratings such as Ex ia, Ex d flameproof, and Ex mb. Single coil or double coil options are available, along with 3/2 and 5/2 port options.
