Pneumatic valve is with air operated valve.

A, pneumatic valve main categories:

1) torque type cylinder valve

2) pneumatic o-type cutting ball valve

3) pneumatic v-type regulating ball valve

4) electric valve

5) pneumatic straight program diaphragm valve

6) electromagnetic diaphragm valve

Second, the pneumatic V type valve: USES and features A, use is A quarter-turn structure, it and valve positioner supporting the use, can realize proportional control; V type valve core is the most suitable for all kinds of control occasions, has the rated flow coefficient is big, adjustable than the big, seal effect is good, regulating performance zero sensitive, small size, can be vertical lie installation. optimum

Used to control gas, steam, liquid, and other media.

B, features: is a quarter-turn structure that consists of V type valve, pneumatic actuators, locator and other accessories is composed; There is a approximation and the ratio of the intrinsic flow feature; Adopts double bearing structure, starting torque is small, has the extremely good sensitivity and induction speed; Super shear capacity.

C, pneumatic piston actuator using compressed air as power supply, through the piston movement drive crank arm for 90 degrees turn to make valve automatic alignment. It's part as: adjusting bolt, actuator housing, crank arm, cylinder block, cylinder shaft, piston, connecting rod, universal shaft.

D, pneumatic control valve work principle: pneumatic control valve, the executing agency and adjusting mechanism composition. Actuator is regulator thrust components, it according to the control signal of the size of the pressure produced corresponding thrust, and promote the regulatory agency action. The body is a pneumatic control valve regulation unit, it directly and adjust medium contact, adjust the fluid flow.
