1, made suitable for large diameter valves ( Such as DN600 above)

2, requiring short length in structure appropriate chooses butterfly valves

3, should not be used for high temperature and high pressure pipeline system, commonly used in ≦ 80 degrees, ≦ 1. 0 mpa crude oil, oil, water and other media.

4, because of the butterfly valve relative to the gate valve, ball Industrial Valves pressure loss is bigger, so the butterfly valve is suitable for the pressure loss is relaxed in the pipe system of

5, in the need for flow control line should choose

6, selection of on-off require fast for butterfly valves

7, usually with mud in throttling control medium, demand structure length is short, opening and closing speed, low voltage cutoff ( Small pressure difference) Recommend using butterfly valves

8, in the two position adjustment, reducing channel, low noise, gasification, there were a small amount of leakage into the atmosphere, corrosive medium, optional butterfly Industrial Valves.

throttling under special circumstances, or seal strict, or serious wear and tear, low temperature, Cryogenic) , and so on and so forth under the condition of using butterfly valve, metal sealing adjusting device of the need to use special design three special eccentric or double eccentric butterfly valve.
