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 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.
Nickel and phosphor treatment to the parts can enhance the anticorrosive performance.
The fireproof design of metal wound gasket compased of stainless steel and graphite can prevent external leakage.
Anti-static design

Floating ball valve design feature:
Live loaded gland flang
Live loading is designed to provide gland load retention, compensating for expected in-service consolidation of packing. A set of belleville spring washers are used on each gland stud to help exert a continuous compressive force on the gland follower flange and therefore reduce fugitive emissions from the stem packing. ARITA standard belleville-spring washers are protected by a weatherproof cap to keep them free from environmental contamination, resulting in a long stable life.
