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.
