Enquire About This Product →B-2971 Triple Eccentric Butterfly Valve
B-2971 triple eccentric butterfly valve has a bidirectional sealing and tight cutting function. This Triple-eccentric structure ensures that the valve plate seal will only contact the seat in the closed state to avoid additional friction and wear. This series of butterfly valves have perfect applicability no matter vacuum or high pressure, low temperature or high temperature. Metal-seated structure has inherent fire safety attributes. Compared with gate valves, globe valves and ball valves , B-2971 can greatly reduce in size, weight and installation requirements, reducing customer construction and maintenance costs. This valve is widely used in industrial pipelines of metallurgy, power, petrochemical, water supply and drainage, and municipal construction where the medium temperature is no more than 600℃,it is used for regulating flow and cutting off the fluid.
