hard metal seated butterfly valve Flange

metal seated butterfly valve (two-way hard-to-hard all-metal hard-sealed butterfly valve) overcomes various shortcomings of ordinary three-eccentric multi-layer metal hard-sealed butterfly valves. Its sealing ring is completely made of metal materials, and there is no PTFE, graphite, rubber The interlayer made of non-metallic materials such as asbestos boards will not cause damage to the sealing ring due to the erosion of high-speed fluid when the valve is fully open or partially open, and can adapt to high temperature (<800C) and low temperature (≥-196°C) ), high pressure (<PN260/Class1500), corrosive, etc., to meet the requirements of various working conditions.
