Also widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, alkali, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries It is used as a regulating and intercepting device on pipelines with equal media.

The wafer butterfly valve is a very versatile valve type. It has two sealing forms: soft seal and hard seal. In the case of the same caliber, the price of hard-sealed wafer butterfly valves will be higher than that of soft-sealed wafer butterfly valves.
Soft-sealed wafer butterfly valves can be made of various materials, such as gray cast iron, ductile iron, cast steel, stainless steel, etc. The material of hard-sealed wafer butterfly valves is limited and can only be made of cast steel or stainless steel. The reason is that the working conditions used by two different sealing types of butterfly valves are different. The soft sealing one can only be used in low pressure and normal temperature environments. Hard seals are mostly used in high pressure and high temperature environments.
