Description of the characteristics of imported pneumatic gate valve

Pneumatic gate valve overview
Pneumatic gate valve, with the valve driven by compressed air, when the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface. It is self-sealing.

Purpose and characteristics of pneumatic gate valve
Uses: A right-angle rotary structure, which is used with the valve positioner to achieve proportional adjustment; V-type spool is most suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect and adjustment performance. Zero sensitivity, small size, can be installed in a vertical position. Suitable for controlling gases, vapors, liquids and other media.
Features: It is a right-angle rotary structure consisting of V-shaped valve body, pneumatic actuator, positioner and other accessories; it has an inherent flow characteristic of approximately equal ratio; double bearing structure, small starting torque and excellent Sensitivity and sensing speed; superior shearing ability.

Pneumatic gate valve structure:
Pneumatic gate valves mainly consist of left and right valve bodies, valve covers, gates, valve stems, sealing rings, double-layer cylinders and their pistons, piston rods, partitions together with buffer mechanism, manual mechanism, pneumatic-manual conversion device and bonnet packing. The device is composed of parts, etc., and the valve opening and closing is completed by the cylinder action.
