• B3200 Series Trunnion Mounted Full Bore Ball Valve
    • Full Bore, large diameter, withstand heavy loads and high pressure, widely used in petroleum, chemical and other industries
    • Features Technical Standards Industries

    • Full bore

      Double bearing design results in reduction of the friction between the ball and the seat, as well as the elimination of the huge load torque caused by the inlet-end medium pressure pushing the ball to extrude the seat

      Relatively low operating torques results in easier operation and lower actuation costs

      Spring loaded seat enhances active sealing. In the event a seat is slightly damaged, the seat maintains close contact with the ball, assuring tight sealing. This results in longer service life benefits

      Fire safety designed. A metal-to-metal secondary sealing (acc. to ANSI Class IV) is formed in the event the soft seat is damaged

      Fire tests acc. to API 607 and API 6FA

      V-shaped gland packing acc. to TUV TA-LUFT

      Automatic cavity pressure relief

      Adjustable stem packing

      Valve structure acc. to API 6D.

      Optional: Supplementary sealing seat structure. In case of emergency, sealants can be injected into this structure.
