Pneumatic Slide Gate Valve

Welcome to buy Pneumatic Slide Gate Valve from us. Every request from customers is being replied within 24 hours. 

With the help of compressed air driven valve, gate valve closed, the sealing surface can only rely on media pressure to seal, that is, rely on media pressure will be the sealing surface of the gate plate to the other side of the valve seat to ensure the sealing surface of the seal, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it depends on external force to force the gate plate to the seat to ensure the sealing of the sealing surface.

It is a right-angle rotary structure, which can be used with valve positioner to realize proportional adjustment; V-type spool is most suitable for various adjustment occasions, with large rated flow coefficient, adjustable ratio, good sealing effect, zero-sensitive adjustment performance, small volume, and can be installed vertically. Suitable for control of gas, steam, liquid and other media. Composed of V-shaped valve body, pneumatic actuator, positioner and other accessories; has an inherent flow characteristic of approximate equal percentage ratio; adopts double bearing structure, small starting torque, excellent sensitivity and induction speed; superb shearing ability.

Working principle of pneumatic regulating valve: pneumatic regulating valve consists of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, which generates the corresponding thrust according to the size of the control signal pressure to push the regulating mechanism action. The valve body is the regulating part of the pneumatic regulating valve, which is in direct contact with the regulating medium to regulate the flow of the fluid.
