Cryogenic Electric Actuated Ball Valves: Overview & Technical Parameters

The Cryogenic Electric Actuated Ball Valve consists of a 304 stainless steel forged valve body and an explosion-proof quarter-turn actuator. It is suitable for the management systems of cryogenic liquid storage and transportation equipment, featuring flexible opening and closing and reliable sealing. It can also be used in management systems of other cryogenic and deep-cooling media. The actuator of the explosion-proof cryogenic electric actuated ball valve is a fully enclosed squirrel-cage motor, which has the advantages of small volume and large torque. The insulation class is Class F, and it is equipped with a built-in overheat protection switch to prevent motor damage. It is also equipped with a handwheel device; the design of the handwheel ensures safety, reliability and labor saving. In the event of power failure, turning the handwheel allows manual adjustment of the opening degree of the cryogenic electric actuated ball valve, and it automatically resets when power is restored.
