                  [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.
