Purpose and characteristics of pneumatic gate valve

　Pneumatic gate valve mainly has the following four characteristics:

A. The utility model is A cartesian rotary structure, which can be matched with the valve positioner for proportional adjustment; V-type spool is suitable for all kinds of adjustment occasions, with rated flow coefficient large, adjustable ratio large, good sealing effect, adjustment performance zero sensitivity, small volume, can be installed vertically. Suitable for controlling gas, steam, liquid and other media.

B. Features: it is a rectangular rotary structure, consisting of v-shaped valve body, pneumatic actuator, positioner and other accessories; There is an intrinsic flow characteristic of approximately equal to one hundred percent; Double bearing structure, small starting torque, excellent sensitivity and speed of induction; Strong shearing ability.

C. The pneumatic piston actuator USES compressed air as the power source to drive the crank arm to turn 90 degrees through the movement of the piston, so as to make the valve open and close automatically. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, universal shaft.

D. Operating principle of pneumatic gate valve: the pneumatic regulating valve is composed of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, it produces the corresponding thrust according to the size of the control signal pressure, and pushes the regulating mechanism to act. 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.
