AOX-VR Series Electric Actuators
“AOX-VR” series explosion-proof electric actuator has compact structure, excellent weather resistance and seismic resistance. When the actuator is powered off, the self-locking transmission mechanism ensures that the valve position remains unchanged, and the electrical and mechanical double limits are set to prevent overtravel. The detachable driving adapter sleeve is convenient for machining, and the bottom mounting size conforms to ISO5211 standard. It is widely used in butterfly valve, ball valve, damper valve, plug valve, shutter valve and various special valves.
