Product Detail

Product description

        The hydraulic fan-shaped blind plate valve is mainly composed of left valve body, right valve body, screw pair, flap, sealing ring, lever, hydraulic cylinder and other parts, and a rigid structure is formed by a base and a supporting column. The valve is equipped with a clamping oil cylinder and a flap oil cylinder. The clamping oil cylinder drives the left and right valve bodies through a lever pair and a screw screw pair to complete the loosening and clamping action, and the flap oil cylinder drives the valve plate to complete the switching action. The rubber sealing ring is embedded in the valve plate, which has the characteristics of high temperature resistance, good sealing performance, easy replacement and long service life.

        This valve can be controlled remotely by a single unit or by multiple units connected to the network. Under abnormal conditions, the valve itself can also be operated manually.
