The manufacturing method of metal hard seal pneumatic ball valve Hard seal pneumatic ball valve is widely used in various harsh medium environments. Due to the particularity of the structure, the processing and assembly requirements in production are relatively high, and leakage often occurs. For the purpose of most enterprises, metal sealed pneumatic ball valves and metal hard sealed pneumatic ball valves are mainly made of left and right valve bodies and then bolted; The sealing structure adopts two independent valve seats for sealing. Since the clearance fit is adopted between the valve seat and the valve body, and the sealing material must be used between the bottom end of the valve seat and the valve body for sealing, so that all parts that need to be sealed may leak, and the clearance around the valve seat provides wear, corrosion and accumulation conditions for the transmission medium in the pipeline.

Application of stainless steel pneumatic butterfly valve
