Purpose of control valve

Control valves are a common type of equipment in industry and engineering. Their main function is to control parameters such as flow, pressure, temperature or liquid level of fluids (liquids, gases or mixtures) in pipeline systems. Specific uses include but are not limited to the following aspects:

Flow control: Control valves can adjust the flow of fluids as needed, such as controlling the supply rate of raw materials in chemical production, or controlling the flow of water in water supply systems.

Pressure regulation: In pipeline systems, control valves can adjust the pressure of fluids and keep it within the design range to ensure the safe operation of equipment and pipeline systems.

Temperature control: In heating or cooling systems, control valves can adjust the temperature of fluids to ensure that the fluid enters the process or equipment at the desired temperature.

Liquid level regulation: In equipment such as storage tanks or reactors, control valves can control the liquid level of liquids to maintain the stability and safety of equipment operation.

Fluid mixing and diversion: In situations where different fluids need to be mixed or diverted, control valves can adjust the entry ratio of each fluid as needed.

Automated control system: Control valves are often used in automated control systems to adjust various parameters of fluids through signals fed back by sensors to achieve precise process control.

In summary, control valves play an important role in industrial production and equipment operation. By precisely controlling fluid parameters, they ensure the stability, safety and efficiency of the process.
