Double block and bleed style(DBB)
Double stem sealing.
The ball can preserve force sealing of CZPT when it is closed or entirely opened.
Shorter higher sleeve reducces bearing load and operation torue
Limit device ensures the exact opening and closing situation of the valve
The vall and stem are divided so as to decrease stem load.
The stem adopts anti-blow-out design.
The sealing floor 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 daily life of the valve.
Stem leakage can be prevented via the emergency grease fitting.

Before we pointed out that when two gears mesh, the scaled-down one is referred to as the pinion. A rack is a straight bar with gear enamel that meshes with the pinion. So you can possibly imagine how rack and pinion gears are employed to change rotation into linear movement. A ideal case in point of this is the steering technique on several automobiles. The steering wheel rotates a gear, which engages the rack. As the gear turns, it slides the rack both to the proper or remaining, based on which way you change the wheel.
EP’s racks convert rotational movement to linear movement when used with spur gears. It is made to function with our stock 14 1/2° and 20° PA spur gears. It can be modified for particular apps, such as drilling and tapping mounting holes, cutting to specific lengths, or matching the ends of two-piece racks to develop constant lengths for a longer time than inventory.
