What fields are valves used in?

Valves are widely used in the following fields:

1. Industrial field: Valves are used to control the flow, pressure and temperature of fluids (liquids or gases) in industrial production processes. Common industrial valves include ball valves, butterfly valves, gate valves, globe valves, etc.

2. Construction field: Valves play an important role in the water supply, gas supply, and drainage systems of buildings. For example, faucet valves used to control water flow, water tank inlet valves, regulating valves used to regulate heating systems, etc.

3. Sewage treatment: Valves are used to control, regulate and isolate the flow of sewage in sewage treatment systems. Common sewage treatment valves include stop valves, butterfly valves, plug valves, etc.

4. Oil and natural gas industry: Valves are used for fluid control in oil and natural gas extraction, transportation and processing, including pipeline valves, ball valves, butterfly valves, etc.

5. Medical equipment: Valves are used in medical equipment, such as infusion devices, ventilators, etc.

6. Automobile industry: Valves are used in automobile engines to control the flow of fuel, valves, etc.

In short, valves are widely used in various industrial and daily life situations where fluid flow and pressure need to be controlled.
