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 vall 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.
Application
