Hard seal worm to clip butterfly valve, worm to clip butterfly valve, to clip butterfly valve

Hard seal worm gear clip butterfly valve, is a sandwich connection, multi-layer metal hard seal butterfly valve, temperature 425℃, model D373H, D373Y, D373W, diameter DN50-DN2000, pressure PN1.0mPA6.4mpa.

Hard seal to the butterfly valve, through the butterfly plate on the multilayer sealing ring (stainless steel sheet and graphite sheet layer of elasticity) to achieve zero leakage seal, sealing ring and valve seat contact surface for oblique conical surface, butterfly plate sealing ring and valve seat between the contact Angle of the slight "wedge effect", the sealing ring occurs soft and radial compression. Due to the uniform contact between the seat and the sealing ring and the flexibility of the sealing ring, the load on the seat is uniform, so that the tightest cut is achieved with the minimum torque

Hard sealed worm gear pair clip butterfly valve is a kind of valve widely used in industrial pipeline system, mainly used for regulating flow and cutting off fluid. The following are the main fields of application: metallurgy, electric power, petrochemical industry: hard sealed worm gear clamp butterfly valve is widely used in metallurgy, electric power, petrochemical and other industrial pipelines with medium temperature ≤425℃, used for regulating flow and carrying and breaking flow. Water supply and drainage and municipal construction: The valve is also suitable for industrial piping systems such as water supply and drainage and municipal construction, for regulating flow and cutting off fluids. Corrosive medium pipeline: for medium temperature ≤550℃ metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage and other corrosive medium pipeline, hard sealed worm gear clip butterfly valve is an ideal device to regulate flow and cut off fluid
