Stainless steel flange three eccentric butterfly valve, flange three eccentric butterfly valve, three eccentric butterfly valve, flange butterfly valve,

Stainless steel flanged three eccentric butterfly valve, is made of corrosion resistant stainless steel, stainless steel material: SS304, SS316, SS316L, DSS2205, DSS2507 duplex steel, 904L, 254SMo, 1.4529 stainless steel. Model D343W, D343Y, nominal pressure: 1.0mp-6.4mpa, nominal diameter DN50-DN2000. Stainless steel flanged three eccentric butterfly valve, by the valve body, butterfly plate, valve stem, sealing ring, actuator and other main components, valve structure using three-dimensional eccentric principle design, hard and soft multi-level seal, seal reliable, can meet all levels of standards, at the same time flow characteristics are good, with adjustment function.

Through the butterfly plate on the multilayer sealing ring (stainless steel sheet and graphite sheet layer of elasticity) to achieve zero leakage sealing, sealing ring and valve seat contact surface for the oblique cone, the butterfly plate sealing ring and the valve body seat of the contact Angle produce a slight "wedge effect", make the sealing ring flexible 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 tight cut is achieved with small torque.

The application range of stainless steel flanged three eccentric butterfly valve includes: industrial pipeline: widely used in the medium temperature ≤425℃ metallurgy, electric power, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines, used to regulate the flow and load and break the flow body. Special working conditions: in throttle, regulation control and mud medium, the structure length is required to be short, and the opening and closing speed is fast. Low pressure cut-off, flange butterfly valve is recommended. When the butterfly valve is used under special working conditions, such as throttle regulation or strict seal requirement, or severe wear and low temperature, it is necessary to use the flange butterfly valve with three eccentric or double eccentric adjustment device with special design metal sealing. Gas separation and chemical industry: The metal to metal surface seal three eccentric butterfly valve is not only used as a large pressure swing adsorption gas separation device program control valve, but also can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, is a good substitute for gate valve, globe valve, etc. Urban infrastructure: metal to metal wire sealing double eccentric flanged butterfly valve is suitable for urban heating, gas supply, water supply and gas, oil, acid and alkali pipelines, as a regulation and closure device. Ventilation and dust removal system: flanged soft eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines, widely used in metallurgy, light industry, electric power, petrochemical systems of gas pipelines and water channels
