Dealt with by the softening of the use of high-strength carbon fiber continuous filament woven and impregnated graphite and special lubricant to form a compact structure, with good self-lubrication, to effectively control the leakage. As a high temperature and high pressure conditions of the pump, valve packing letter can be used alone, but also with other Central graphite packing, graphite packing ring used in combination for the side ring, can be anti-extrusion.
      

         Widely used in power plants, refineries, boiler plant, water, steam, acids, alkalis and many other media. For steam turbines, high temperature electric valve, and the general application of high temperature and high pressure valves.
