Pneumatic gate valve

The Z6S41 series pneumatic with manual wedge gate valve is a low bracket open gate valve with pneumatic actuator (double cylinder, with buffer mechanism) and manual and protection mechanism (manual and self-locking pneumatic-manual conversion device). Due to the double-layer cylinder structure, the valve has doubled the lifting force compared to the single-cylinder pneumatic gate valve. This fundamentally solves the disadvantage that some valve cylinders of single-cylinder pneumatic gate valves are wedged and cannot be opened. Moreover, since the valve is provided with a buffer mechanism, the valve can be effectively decelerated, and when the valve is closed, the sealing surface of the valve plate and the sealing surface of the valve body are worn due to the downward impact of the piston, and the phenomenon of the gate jam can be avoided. .
