This butterfly valve features a compact, lightweight structure with a concentric/double-eccentric design, delivering low flow resistance and stable sealing performance. Made from ductile iron, cast steel or stainless steel, it is mainly used for on-off and throttling control of media such as water, gas, oil, sewage and weak corrosive fluids. Suitable for medium and low-pressure working conditions, it supports manual, pneumatic and electric actuation for flexible operation. Widely applied in water supply and drainage, HVAC, chemical engineering, metallurgy and pipeline systems, it offers easy installation, low torque and long service life. Strictly tested for sealing and pressure resistance, it ensures reliable operation under various industrial working conditions, providing efficient and stable fluid regulation for pipeline projects.
