Valves are control components in fluid conveying systems.
Definition and Function of Valves
Valves are control components in fluid transportation systems used to control the flow of fluids such as gases, liquids, vapors, etc. They can be used to open or close pipelines, control fluid flow, regulate fluid flow, and control fluid pressure and temperature. There are various types of valves, which can be divided into shut-off valves, check valves, regulating valves, etc. based on their functions and uses.
Classification of valves
Valves can be classified according to different standards, including:
According to their functions and purposes: shut-off valves, check valves, regulating valves, vacuum valves, special purpose valves, etc.
According to the main parameters: nominal pressure (vacuum valve, low-pressure valve, medium pressure valve, high-pressure valve, ultra-high pressure valve), working temperature (ultra-low temperature valve, normal temperature valve, medium temperature valve, high temperature valve), driving mode (automatic valve, power driven valve, manual valve), nominal diameter (small diameter valve, medium diameter valve, large diameter valve, extra large diameter valve), structural characteristics (truncated gate shape, plug and spherical shape, gate shape, swing shape, butterfly shape, slide valve shape), connection method (threaded connection, flange connection, welding connection, clamp connection, sleeve connection, clamp connection), valve body material (metal material valve, non-metallic material valve), etc.
