EXC(G)1/A/B series basic type explosion-proof quarter turn small electric actuator

Short Description:

Ex series angular stroke explosion-proof electric actuator is a device to switch valves by rotating 90° through the output shaft, which is mainly used to drive and control the valve opening of angular stroke.Such as butterfly valve, ball valve, plug valve and other similar valve applications. EXC(CG) output torque range is 35-80N.m.EX series explosion-proof electric actuators can be widely used in petroleum, chemical industry, water treatment, shipbuilding, paper making, power station, heating, building automatic control and other industries.
