Double block and bleed layout(DBB)
Double stem sealing.
The ball can keep force sealing of CZPT when it is closed or fully opened.
Shorter upper sleeve reducces bearing load and operation torue
Limit system ensures the precise opening and closing position of the valve
The vall and stem are divided so as to decrease stem load.
The stem adopts anti-blow-out design and style.
The sealing area is inserted into te metallic seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Lessen the opening torque and lengthen the support existence of the valve.
Stem leakage can be prevented by way of the unexpected emergency grease fitting.

The goal guiding the rack is to change rotational motion into linear motion, the rack runs by means of a pinion (a cylindrical gear that meshes with the rack), so this setup is typically referred to as a rack and pinion. When running gears and racks, equipment oil is also very suggested to increase functionality and longevity. We also stock a vast variety of metric spur gears and offer almost each energy transmission merchandise on the market
There are several varieties of gears, and the most frequent classification technique is by equipment shaft. Typically, there are 3 varieties of the parallel axis, cross-axis, and staggered axis. 1) Parallel shaft gears: such as spur gears, helical gears, internal gears, racks, and helical racks, and so forth. 2) Cross shaft gears: straight bevel gears, spiral bevel gears, zero-diploma bevel gears, etc. 3) Staggered shaft gears: There are staggered shaft helical gears, worm gears, hypoid gears, and so forth.
