The valve is composed of DCL series of fine and small electric actuator and ultra short ball valve, and general electric ball valve has a compact structure, small size, light weight, the valve seat and face flange distance near, less material retention. Superior sealing performance and other characteristics. Usually applied to the strict requirements of the occasions, widely used in chemical, petroleum, pharmaceutical, light industry and other industries of automatic control. The V type channel sphere structure and the electronic electric actuator can realize the regulation of the flow. Q71 super thin ball valve is a part, with a short structure, light weight, easy installation, saving materials, and other significant advantages.
