The purpose of instrument pneumatic valve

instrument pneumatic valve is a kind of pipe accessories. It is used to change the channel cross-section and flow direction of medium, the medium flow control of a device. In particular, instrument pneumatic valve has the following several ways:
( Connected or truncated medium pipeline. Pneumatic valves such as gate, globe pneumatic valve, pneumatic ball valve, plug valve, pneumatic diaphragm valve, pneumatic butterfly valve, etc.
( Adjust and control the medium inside the pipeline flow and pressure. Such as throttle pneumatic valve, regulating valve, vacuum pneumatic valve, safety valve, etc.
( Change the direction of the medium flow in the pipeline. Such as distribution of pneumatic valve, three-way cock, three-way or four-way solenoid, etc.
( To prevent the medium flow backwards. Such as different structure of check pneumatic valve, hand movement valve, etc.
( Separation medium. Such as different structure of pneumatic valve, steam trap air hydrophobic pneumatic valve etc.
( Instructions and liquid level height adjustment. Such as liquid level indicator, liquid level controller, etc.
( Other special purposes. Such as temperature control pneumatic valve, over-current protection emergency cut-off valve, etc. （ According to cheung network building materials)
