Soft seal butterfly valve

This soft seal butterfly valve adopts an elastic soft sealing structure with a rubber or polymer sealing ring, providing excellent zero-leakage performance and low operating torque. Made of ductile iron and stainless steel, it is suitable for on-off and throttling control of media such as water, sewage, air and mild corrosive fluids in medium and low-pressure working conditions. Featuring a compact wafer or lug structure, smooth flow channel and easy installation, it is widely used in water supply and drainage, HVAC, chemical and general industrial pipeline systems, and can be equipped with manual, pneumatic or electric actuators for flexible operation. Strictly tested for tightness and pressure resistance, it delivers stable performance and long service life for conventional fluid control scenarios.
