Product Detail

Product overview

The hydraulic fan-shaped blind valve is mainly composed of the left valve body, the right valve body, the lead screw pair, the flap, the sealing ring, the lever, the hydraulic cylinder and other parts, and a rigid structure is formed by the base and the support column. The valve is provided with a clamping oil cylinder and a flap oil cylinder. The clamping oil cylinder drives the left and right valve bodies to complete the loosening and clamping actions through the lever pair and the screw pair, 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, convenient replacement and long service life.


The valve can be controlled remotely by a single unit or by multiple units connected to the network. In abnormal circumstances, the valve itself can also be used for manual operation.
