Double block and bleed layout(DBB)
Double stem sealing.
The ball can preserve stress sealing of CZPT when it is closed or fully opened.
Shorter upper sleeve reducces bearing load and procedure torue
Restrict device assures the precise opening and closing place of the valve
The vall and stem are separated so as to lessen stem load.
The stem adopts anti-blow-out layout.
The sealing surface area is inserted into te metallic seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Minimize the opening torque and extend the support existence of the valve.
Stem leakage can be prevented through the crisis grease fitting.

Racks are utilized to change rotary movement into linear motion. The spur teeth of the rack cut into one face of the sq. or circular rod part and perform with the pinion, which is a little cylindrical equipment that meshes with the rack. Typically, racks and pinions are collectively referred to as “rack and pinion”.
