Double block and bleed design(DBB)

  • Double stem sealing.
  • The ball can maintain pressure sealing of pipeline when it is closed or fully opened.
  • Shorter upper sleeve reducces bearing load and operation torue
  • Limit device ensures the accurate opening and closing position of the valve.
  • The ball and stem are separated so as to reduce stem load.
  • The stem adopts anti-blow-out design.
  • The sealing surface is inserted into te metal seat by polymer or plastic
  • The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
  • Reduce the opening torque and prolong the service life of the valve.
  • Stem leakage can be prevented through the emergency grease fitting.
