Hard seal butterfly valve

Hard seal butterfly valve

This hard seal butterfly valve adopts a metal hard sealing structure with eccentric design, featuring high temperature resistance, wear resistance and reliable zero-leakage performance. Made of ductile iron, cast steel or stainless steel with hardened sealing surfaces, it is suitable for on-off and throttling control of media such as steam, high-temperature oil, gas, dust-containing fluids and mildly corrosive medium. Designed for high-temperature, high-pressure and harsh working conditions in petroleum, chemical, metallurgy, electric power and heating systems, it has stable operation, small flow resistance and long service life. Supporting wafer, lug and flanged connections as well as manual, pneumatic and electric actuation, it provides durable and dependable fluid control for heavy-duty industrial pipeline applications.
