Instrument valves are control devices for fluid pipelines, whose basic function is to connect or cut off the flow of medium in the pipeline, change the flow direction of the medium, adjust the pressure and flow rate of the medium, and protect the normal operation of equipment in the pipeline.

The widespread application of industrial instrument valves dates back to Watt's invention of the steam engine. In the past two to three decades, higher requirements have been placed on instrument valves due to the needs of petroleum, chemical, power plant, metallurgy, shipbuilding, nuclear energy, aerospace, and other fields. This has prompted people to research and produce high parameter valves, from carbon steel to titanium and titanium alloys, high-strength corrosion-resistant steel, etc. The driving methods of instrument valves have evolved from manual to electric, pneumatic, hydraulic, programmable, numerical control, remote control, etc.

With the continuous development of modern industry, the demand for instrument valves is constantly increasing. A modern petrochemical plant requires tens of thousands of various types of valves, and the use of instrument valves is very large. Instrument valves are widely used in various industrial fields, almost involving various areas of industrial production. In these fields, the role of instrument valves is crucial. It can not only control the flow and pressure of fluid media, but also ensure the safe operation of production equipment, effectively reduce production costs, and improve production efficiency.

In summary, instrument valves play an irreplaceable role in the industrial field. Each industry needs to choose suitable instrument valves according to different production needs to ensure the normal operation of production equipment, improve production efficiency, reduce costs, and ensure the safety of industrial production.
