Valve classification are: general classification of the valve by pressure categories, classified by the medium temperature, body material classified by the four.

This classification not only by theory, the role of the structure divided by another, is the international, the most commonly used classification methods. General sub-gate valve, globe valve, throttle, instrument valves, piston valves, diaphragm valves, plug valves, ball valves, butterfly valves, check valves, pressure reducing valve safety valve, steam trap, control valve, foot valve, filters, drain valve and so on.
