Explosion proof quick open electric actuator / ExdⅡC T4 grade for Zone 1 and Division 1
Features
Description
DCL explosion proof quick open electric actuators are widely used in environment with flammable gases to drive butterfly valves and ball valves. Kinds of output speed are optional per automation system requirements. Since multi head worm gear is used to improve transmission efficiency, we add relay inside actuator to ensure no leakage and no back drive when driving butterfly valves.
