brief introduction

Metal hard seal butterfly valve adopts elastic seal ring multi-layer metal hard seal structure, which is widely used in metallurgy with medium temperature < 350C. Power, petrochemical, water supply and drainage and municipal construction and other industrial pipelines are used to regulate flow and cut off fluid. The metal hard seal butterfly valve adopts three eccentric sealing structure, and the valve seat and screw plate almost have no wear and tear. The sealing group is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life, no matter at low and high temperature.
