Introduction to Pneumatic Switching Valve

General:

The pneumatic on-off valve is mainly used for switching in the powder material flow control system. Usually used in series with a flow control valve. Pneumatic switching valve realizes switching action by taking cylinder as power.

In structure, there is no difference between the valve body of pneumatic switch valve and electric switch valve. The main difference is that the driving force pushing the slider in the valve body to change the valve position is different. The pneumatic switching valve is sent by the control air in the air circuit (pipe) to the operating cylinder in the valve to push the piston to move and drive the slider to change the valve position of the valve body; The electric switch valve generates electromagnetic suction through the spiral coil to drive the slider to change the valve position of the valve body.

As the pneumatic switch valve changes the valve position by forming a certain pressure through the control air in the cylinder to push the piston and slider to change the valve position of the valve body, the opening and closing speed is relatively slow during actual control, while the suction generated by the electric switch valve current is relatively fast, so the electric switch valve moves fast from the working speed.

In addition, the control signal connected to the pneumatic switch valve is the air pressure signal, which must be connected with pipes and has a large volume; The control signal of the electric switch valve is generally the current signal, which can be connected by wire, and there is no operating plunger, so the volume of the electric switch valve is smaller than that of the pneumatic switch valve.
