      [Valve features]
             Butt welding ball valve is divided into integral (one piece), two - stage and three - stage. The valve body casting adopts the advanced technology imported from Taiwan. The structure is reasonable and the shape is beautiful. The valve seat adopts an elastic sealing structure, with reliable sealing and easy opening and closing. The stem seal downloading inverted structure, abnormal pressure of the valve chamber, the stem will not be out. Two piece, three piece ball valve, three piece ball valve connection form, another butt welding (BW) socket welding (SW), and all can bring international standard ISO bracket platform and locking device. The 90 switch positioning mechanism can be provided, and the lock is locked according to the requirement to prevent misoperation.

      [Adaptive condition]
      The valve is an important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, tank equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
