1、 Main types of pneumatic valves:

1) Pneumatic V-type regulating ball valve

2) Pneumatic O-ring cut-off ball valve

3) Torque cylinder ball valve

4) Solenoid diaphragm valve

5) Pneumatic straight travel diaphragm valve

6) Electric valve

2、 Pneumatic V-type regulating valve:

Purpose and characteristics

A. The utility model is a right angle rotation structure, which can be used together with the valve positioner to realize proportional adjustment; V-shaped valve core is suitable for various adjustment occasions. It has large rated flow coefficient, large adjustable ratio, good sealing effect, zero sensitivity adjustment performance, small size, and can be installed vertically and horizontally. It is suitable for controlling gas, steam, liquid and other media.

B. Features: It is a right angle rotary structure, composed of V-shaped valve body, pneumatic actuator, positioner and other accessories; There is an inherent flow characteristic of approximately equal percentage; Double bearing structure, small starting torque, excellent sensitivity and induction speed; Super shearing capacity.

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

D. Working principle of pneumatic control valve: pneumatic control valve is composed of actuator and regulator. The actuator is the thrust component of the regulating valve, which generates the corresponding thrust according to the control signal pressure to push the regulating mechanism to act. The valve body is the regulating part of the pneumatic control valve, which directly contacts with the regulating medium to regulate the flow of the fluid.
