[Essential information]
Welding of J shaped elastic precision of the sealing ring and the three eccentric multi-level metal seal structure type metal seal butterfly valve, is widely used in medium temperature ≤425℃, petroleum chemical industry, metallurgy, electric power and water supply and drainage and municipal construction and other industrial pipelines, adjust the flux and set off fluid. The three eccentric valve structure, valve seat and disc sealing surface are made of stainless steel with different hardness, good corrosion resistance, long service life, the two-way valve seal military postal function, valve product line with national GB/T13927-92 pressure test standard.

[Valve features]
1, the use of three eccentric structure design, this design makes the valve for high temperature, high pressure, fire application, bubble level sealed ideal hard sealing butterfly valve.
2, because of the use of welded structure, so that the valve and pipe plane to achieve permanent zero leakage.
3, This valve has no flange and brings great convenience and beauty to the pipe and the thermal insulation.
[Adaptive condition]
Now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, canned equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, is the preferred product construction the construction of national defense science and technology.
