Description

Three-Piece Trunnion Ball Valve Pneumatic Flanged Ball Valve in three-piece body, Trunnion Mounted Ball Valve.It is designed as per APl16D specification and fire tested as per APl6FA standard, applicable for various applications in oil and natural gas industry and it is in forged steel body and bonnet design to solve the inevitable defection of casting steel and can ensure a stable and reliable performance under full differential pressure. Besides the trunnion mounted ball design, it is with spring loaded seat to ensure good tightness under low differential pressure and low opera -tion torque requirement. Special seat design for Low temperature or high temperature application is available.

Three-Piece Trunnion Ball Valve Pneumatic Flanged Ball Valve
Feature
  • Fire-safe design,when non-metal material damaged by high temperature,pipe middle-upper pressure push ball to metal seat lip to cut off medium to avoid internal leakage.
  • Blow-out proof design ensures the shaft safety under any pressure,and upper sealing function making sure the further reliable packing sealing.
  • Locking device is for option which is designed to provide system protection by preventing mal-operation
  • ISO5211 actuator mounting pad,easy disassembling and maintenance, also can be realized with worn gear, electric actuator or pneumatic actuator etc
  • Removable hand lever design for convenient operation,valve is also easy to be assembled with actuator and accessories for on-off or control application.
