Heating steam jacketed buttefly valve also known as jacket insulation butterfly valve,Heating steam jacketed buttefly valve is in the ordinary tripple eccentric metal hard seal butterfly valve on the basis of the external welding of the metal jacket, in the Heating steam jacketed buttefly valve body on both sides of the jacket interface can contain steam or other overheating gas, in order to prevent the medium in the normal temperature of solidification or crystallization.Heating steam jacketed buttefly valve flange is bigger than ordinary metal hard seal butterfly valve flange to one to two specifications, Heating steam jacketed buttefly valve mainly used in petroleum, chemical, metallurgy, pharmaceutical and other systems.
 
Heating steam jacketed buttefly valve features:
1 Heating steam jacketed buttefly valve adopts three eccentric sealing structure, seat and butterfly disc almost no wear, with more and more tight sealing function.
2 the seal ring is made of stainless steel, with the dual advantages of metal hard seal and elastic seal, regardless of the low temperature and high temperature, Heating steam jacketed buttefly valve have excellent sealing performance, corrosion resistance, long service life and other characteristics.
3 The sealing surface of the Heating steam jacketed buttefly valve disc is hard faced with cobalt-based carbide, which is resistant to wear and has a long service life.
4 Large size Heating steam jacketed buttefly valve adopts the structure of quilting, with high strength, large flow area and small flow resistance.
5 Heating steam jacketed buttefly valve has a two-way sealing function, installation is not limited by the flow of the medium, nor by the impact of the space position, can be installed in any direction.
6 The driving device of Heating steam jacketed buttefly valve can be installed in multiple stations (rotating 90° or 180°), which is convenient for users to use.
