What are the types of valves and their general classification?

Classification of valves by application or primary structural features.

The general classification system, which categorizes valves based on both principle and function as well as structure, is currently the most widely used classification method both domestically and internationally. Valves are generally classified into the following types: gate valves, globe valves, plug valves, ball valves, butterfly valves, diaphragm valves, check valves, throttle valves, safety valves, pressure reducing valves, steam traps, and control valves.
