What is the function of the valve? (one)

2022 12/19

Valves are generally divided into automatic valves and actuated valves. Automatic valves (such as safety valves, pressure reducing valves, steam traps and check valves) rely on changes in the medium pressure of equipment or pipelines to achieve the purpose of opening and closing. The valve (gate valve, globe valve, ball valve, butterfly valve, etc.) is driven by the driving device (manual, electric, hydraulic, pneumatic, etc.) to adjust the pressure, flow and direction of the medium in the pipeline. Due to the different pressure, temperature, flow and physical and chemical properties of the medium, the control requirements and use requirements for the equipment and piping system are also different, so the functions of the valves are also different.

1. Cut-off effect
The important function of the valve is the cut-off effect. It closes (closes) the fluid in the pipeline and does not allow it to flow. Generally, the valves of various pipelines mainly play a cut-off role.

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