Double block and bleed design(DBB)
Double stem sealing.
The ball can maintain strain sealing of CZPT when it is closed or completely opened.
Shorter upper sleeve reducces bearing load and procedure torue
Limit unit assures the correct opening and closing place of the valve
The vall and stem are separated so as to minimize stem load.
The stem adopts anti-blow-out design.
The sealing area is inserted into te metal seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Lessen the opening torque and lengthen the support life of the valve.
Stem leakage can be prevented via the emergency grease fitting.

Before we mentioned that when two gears mesh, the smaller sized a single is referred to as the pinion. A rack is a straight bar with equipment tooth that meshes with the pinion. So you can possibly picture how rack and pinion gears are used to convert rotation into linear motion. A ideal instance of this is the steering method on several cars. The steering wheel rotates a equipment, which engages the rack. As the equipment turns, it slides the rack possibly to the correct or left, depending on which way you change the wheel.
Racks, when utilised with spur gears, change rotational movement to linear motion. EP Gear’s racks are developed to perform with our stock fourteen 1/2° and 20° PA spur gears. Usually, racks are modified to fit particular applications. This may contain drilling and tapping mounting holes, slicing to a distinct length, or matching the ends of two racks to develop a more time steady length than stock.
