Double block and bleed design and style(DBB)
Double stem sealing.
The ball can sustain pressure sealing of CZPT when it is closed or totally opened.
Shorter higher sleeve reducces bearing load and procedure torue
Limit system guarantees the accurate opening and closing position of the valve
The vall and stem are divided so as to minimize stem load.
The stem adopts anti-blow-out style.
The sealing floor is inserted into te steel seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Minimize the opening torque and prolong the service daily life of the valve.
Stem leakage can be prevented via the unexpected emergency grease fitting.

The tooth surface hardness, it is divided into comfortable tooth area gear transmission and hard tooth area equipment transmission. When the tooth surface hardness of the two wheels (or 1 of them) is much less than or equivalent to 350HBW, it is referred to as comfortable tooth floor transmission when the tooth surface area hardness of the two wheels is >350HBW, it is referred to as difficult tooth area transmission. Soft-tooth area gear transmission is often used for common low-speed equipment transmission that does not need high precision, and difficult-toothed surface equipment transmission is usually utilized for gear transmission that calls for powerful bearing capability and compact structure.
Racks are utilised to convert rotary movement into linear movement. The spur enamel of the rack minimize into one experience of the square or round rod part and function with the pinion, which is a little cylindrical equipment that meshes with the rack. Generally, racks and pinions are collectively referred to as “rack and pinion”.
