1.Cut-off effect
The important role of the valve is to cut off the effect. It is to close (close) the fluid in the pipeline, will not make it flow, in general, the valve of various pipelines mainly play a cut-off role.

2. Regulating role
Another important role of the valve is to regulate the flow, according to the working conditions or requirements to adjust the medium flow, temperature, pressure, level and other parameters, flow control depends on the size of the valve opening adjustment.

3. Non-reverse effect
Some pipelines require medium flow in one direction and do not allow backflow or backward banding. This requires the use of check valves (or check valves). It is a valve that automatically opens and closes the valve flap to prevent backflow of the medium. It is a kind of automatic valve. Its main function is to prevent the reverse flow of the medium, to prevent the reverse rotation of the pump and drive motor and the release of the container medium.

4. Safety role
When the fluid pressure is too high, in order to prevent the pressure in the high pressure vessel exceeds the pressure limit of the vessel, an explosion may occur. Therefore, the valve that can automatically release pressure at a certain pressure is installed on the vessel, usually called a safety valve. For example, safety valves are installed on boilers, compressed air tanks and some high-pressure reactors. This valve plays a role in ensuring safety.

5. Other functions
In addition to the above four functions, the valve also has a number of functions, such as stabilizing the system pressure; depressurizing the high pressure in front of the valve to a reduced pressure, allowing the exhaust to be depressurized and discharging contaminants from the discharge function. Samples are taken for analysis and observation; and a portion of the fluid is returned to the previous backflow process for reflux. There are also steering valves (*-way valves, *-way valves, etc.) that transfer fluid to another line.
