Design description
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 reduces bearing load and operation torque
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 metal backed 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.
Nickel and phosphor treatment to the parts can enhance the anticorrosive performance.
The fireproof design of metal wound gasket of stainless steel and
graphite can prevent external leakage.
