Are Butterfly Valves Suitable For High Pressure?

Normal butterfly valves are not suitable for high pressure, but specially designed butterfly valves can be used in high pressure environments. The specific analysis is as follows:
Normal butterfly valves are generally suitable for working conditions with a working pressure of less than 1.6MPa. Some specially designed butterfly valves, such as metal hard seal butterfly valves, operate at a pressure of up to 2.5MPa, while high pressure butterfly valves (such as the 3eccentric metal hard seal butterfly valves) can cover a working pressure from vacuum to ultra-high pressure and can withstand a high pressure of 15MPa to 200MPa. The butterfly valve is designed to operate in a high temperature and high pressure environment by optimizing structural design (e.g., tri-eccentricity) and adopting special sealing materials (e.g., multi-layer soft stack seal, soft T-ring and stainless steel composite seal).
Ordinary butterfly valves has problems of insufficient sealing performance and limited structural strength under high pressure. High-pressure butterfly valve can be replaced by technical improvement of gate valves and ball valves and used in petroleum, chemical industry, metallurgical and other high-pressure pipeline systems. butterfly valve must be selected according to the specific pressure, temperature and media conditions to ensure that its performance in line with working conditions.
