What are the characteristics and uses of the pneumatic control valve in the description of the pneumatic control valve?

1. Uses and features of pneumatic control valve: It is a right-angle reversal layout, used in conjunction with a valve positioner to achieve share adjustment; V-shaped spool is most suitable for various adjustment occasions, with a large rated flow coefficient and a large adjustable ratio. , Good sealing, active adjustment function, small size, can be installed vertically. Suitable for controlling gas, steam, liquid and other media.

2. The characteristics of the pneumatic control valve: it is a right-angle reversal layout, consisting of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories; it has a similar inherent flow characteristic of equal percentage; choose a double bearing layout, the starting torque is small , excellent activity and induction speed; super shearing ability.

3. The pneumatic piston actuator uses compressed air as the power source, and the crank arm is rotated 90 degrees through the movement of the piston, so that the valve can be automatically opened and closed. Its components are: adjusting bolt, actuator box, crank arm, cylinder, cylinder shaft, piston, connecting rod, universal shaft.

4. The working principle of the pneumatic control valve: the pneumatic control valve is composed of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, which generates corresponding thrust according to the pressure of the control signal to advance the action of the regulating mechanism. The valve body is the part of the pneumatic regulating valve, which directly contacts the regulating medium and regulates the flow of the fluid.
