Pneumatic control valve:
pneumatic air control valve are pneumatic components that control and adjust the flow direction, pressure and flow of compressed air. They can be used to form various pneumatic circuits, so that the pneumatic actuators can work normally according to the design requirements.
Commonly used pneumatic control valve:
Similar to hydraulic control valves, commonly used basic pneumatic control valves are divided into: pneumatic directional control valve, pneumatic pressure control valve and pneumatic flow control valve. In addition, there are pneumatic logic elements that can realize various logic functions by changing the direction and on-off of the air flow.
1 Pneumatic directional control valve:
Pneumatic directional control valve is a pneumatic component used to control the flow direction of compressed air and air circulation and interruption.
1.1 Classification of pneumatic directional control valves
The pneumatic directional control valve is similar to the directional control valve of the hydraulic system, and it is also divided into a one-way valve and a reversing valve, and its classification method is basically the same. However, because the pneumatic transmission has its own unique characteristics, the pneumatic directional control valve can be classified according to the valve core structure and control method.
a. Shut-off directional control valve
b. Spool type directional control valve
