    Features

    Electric fan-shaped blind valve is mainly composed of left valve body, right valve body, fan-shaped gate, stainless steel bellows, electric drive device, electric clamping device and other parts. The valve body adopts a three-point locking sector gate structure. The sealing part adopts stainless steel and rubber sealing ring, which has good sealing performance and long service life. Electric operation, stable work, flexible start and reliable action. The clamping mechanism adopts screw nut for clamping, with good self-locking. The electric fan-shaped glasses valve is equipped with stainless steel bellows, which has the characteristics of strong scalability and long service life.
