Pneumatic control valve refers to the pneumatic system to control the pressure, flow and flow direction of the air flow, and to ensure the pneumatic actuator or the normal operation of all kinds of pneumatic components. A component that controls and regulates the pressure of compressed air is called a pressure control valve.

Function and application of pneumatic valve system
Pneumatic actuators are divided into two types: single action type and single action type. Double acting pneumatic actuator: two type valve opening and closing control. Single acting pneumatic actuator (spring reset type): the gas cut off or failure, the valve automatically open or close.

Valve: valve is the control component in the fluid delivery system.

Electromagnetic valve: divided into single electronic controlled solenoid valve and double electronically controlled solenoid valve. Single electronically controlled solenoid valve: power supply valve open or close, power off valve closed or open. Double electronically controlled solenoid valve: a coil to open the valve when electricity, and the other coil to power, the valve closed.

4. Limit switch: the signal of the switch position of long-distance transmitting valve. It has mechanical, close and inductive type.

Gas and electricity locator: according to the current signal (standard 4-20mA) size of the valve medium flow adjustment control.
The air FRL: including air valve, filter, oil mist, on the gas regulator, cleaning and lubrication effect.

The manual operation mechanism: automatic control in the normal condition of manual operation.

The muffler: solenoid valve installed on the exhaust port, reduce noise.

9: quick connector is connected to the electromagnetic valve or actuator, the other end will be directly inserted into the trachea can be used.

The air compressor is compressed air pressure generating device.

11. trachea: hose, copper tube, stainless steel. Commonly used specifications are 6mm, 8mm.
