Stainless steel pneumatic butterfly valve has a very broad application in the cooling water system of petrochemical, water treatment, gas, and thermal power stations. This is mainly because its structure is more suitable for making large diameter valves, and its service life is very long, of course, There is also a more prominent shortcomings, that is, it is difficult to completely seal.
For stainless steel pneumatic butterfly valves and stainless steel pneumatic gate valves, it is believed to be a problem with many people, and we will mainly analyze the differences in performance.
1. The sexy of the gate valve is better than the stainless steel pneumatic butterfly valve, of course, this is not absolute, some manufacturers' stainless steel aerodynamic butterfly valve is good.
2, the size of the gate valve is large, the occupancy is also large, the pneumatic butterfly valve is small, and the space is also small.
3, the nominal diameter is greater than 50 to select a butterfly valve, and can not be used.
4, the service life of the stainless steel pneumatic butterfly valve is longer than the service life of the gate valve.
