High temperature hard seal butterfly valve, hard seal butterfly valve, high temperature butterfly valve

High temperature hard seal butterfly valve, multi-layer metal seal, with high temperature heat sink, applicable temperature 550℃, medium: high temperature water, high temperature gas. Model D73Y, diameter DN50-DN800, pressure PN1.0MPa-6.4MPa. Material: carbon steel, chromium molybdenum steel, CF8, CF8M, CF3, CF3M, 2205,2507,904L, 1.4529, 254SMo stainless steel.

The high temperature hard seal butterfly valve is surfacing with high temperature resistant Stellite alloy on the valve seat of the body. The valve plate is fixed with a multi-layer soft stack sealing ring composed of stainless steel sheet and high temperature resistant non-metallic material, and the sealing pair is high temperature resistant and zero leakage. High temperature hard seal butterfly valve, can be equipped with electric and pneumatic, easy to operate, open and close without friction, close with the increase of the torque of the transmission mechanism to compensate for the seal, improve the sealing performance of the butterfly valve and extend the service life.

High temperature hard seal butterfly valve because of its unique structure and material, suitable for a variety of harsh conditions, the specific application range includes: high temperature and high pressure system: Suitable for steam pipelines (such as thermal power plants, chemical boilers), high temperature heat transfer oil, high temperature flue gas, temperature range is usually up to -20℃~450℃, some special materials (such as nickel-based alloy) can withstand high temperature above 600℃ 1. High pressure difference and wear-resistant scene: suitable for slurry containing solid particles (such as mine mineral processing, sewage treatment), high flow rate gas (such as compressed air pipe network, gas transportation), liquid containing crystals or fibers (such as chemical solution, papermaking black liquor). Corrosive medium environment: suitable for acid, alkali solution (such as hydrochloric acid, sulfuric acid, sodium hydroxide), seawater, salt spray and other corrosive fluids. By matching corrosion resistant alloys such as 316L stainless steel, dual phase steel, Hastelloy alloy, hard seal butterfly valve can be used for long term operation in strong corrosion environment. Large-caliber pipeline system: in the large-caliber pipeline above DN300, the hard-seal butterfly valve is more easy to realize automatic control (such as supporting electric or pneumatic actuators) than gate valve and globe valve because of its compact structure, small flow resistance and low opening and closing moment. It is common in the water supply and drainage pipe network and metallurgical blast furnace gas pipeline. Specific industry application: including metallurgy, building materials, chemical industry, power station, glass and other industries in the high temperature gas pipeline, as a high temperature gas medium flow regulation or cutting device; It is widely used in petrochemical, electric power, metallurgy, pharmaceutical and food, water treatment and environmental protection, papermaking and building materials industries
