Double block and bleed design and style(DBB)
Double stem sealing.
The ball can keep pressure sealing of CZPT when it is closed or completely opened.
Shorter upper sleeve reducces bearing load and procedure torue
Restrict unit guarantees the precise opening and closing position of the valve
The vall and stem are divided so as to reduce stem load.
The stem adopts anti-blow-out layout.
The sealing floor is inserted into te metallic seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Reduce the opening torque and prolong the service daily life of the valve.
Stem leakage can be prevented through the crisis grease fitting.

Racks are utilised to change rotary motion into linear movement. The spur tooth of the rack lower into one experience of the square or round rod segment and work with the pinion, which is a tiny cylindrical gear that meshes with the rack. Usually, racks and pinions are collectively referred to as “rack and pinion”.
Equipment racks attribute business standard fourteen-1/2° strain angle for programs the place handle of backlash is essential (will not work with 20° spurs). Precision machining for minimum heart length variation and improved concentricity of mating spur gears. These equipment racks can be modified for specific applications such as drilling and tapping mounting holes, chopping to particular lengths, or matching finishes of two parts of rack to produce a constant duration lengthier than inventory.
