Working principle of pneumatic valve:
1. The pneumatic piston actuator uses compressed air as the power source, and drives the crank arm to rotate 90 degrees through the movement of the piston. To achieve automatic opening and closing of the valve. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, and universal shaft.
2. 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. It generates corresponding thrust according to the control signal pressure and promotes the action of the regulating mechanism. The valve body is the regulating component of the pneumatic regulating valve. It is in direct contact with the regulating medium and regulates the flow of the fluid.
