[Product Usage] The clamp type hard sealed butterfly valve adopts a precise J-shaped elastic sealing ring and a three-level metal hard sealing structure with three eccentricities. It is widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction with a medium temperature of ≤ 425 ℃, for regulating flow rate and carrying flow interruption. [Product features] 1. The clamp type hard sealed butterfly valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter and tighter as it is observed 2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperature conditions, corrosion resistance, and long service life 3. The sealing surface of the butterfly plate is made of cobalt based hard alloy by overla…
