Double block and bleed style(DBB)
Double stem sealing.
The ball can keep stress sealing of CZPT when it is closed or fully opened.
Shorter higher sleeve reducces bearing load and procedure torue
Limit device makes certain the correct opening and closing place of the valve
The vall and stem are divided so as to minimize stem load.
The stem adopts anti-blow-out design.
The sealing surface area is inserted into te steel seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Minimize the opening torque and lengthen the service life of the valve.
Stem leakage can be prevented by means of the emergency grease fitting.

EP’s racks change rotational motion to linear motion when used with spur gears. It is created to work with our inventory 14 1/2° and 20° PA spur gears. It can be modified for specific programs, these kinds of as drilling and tapping mounting holes, slicing to specific lengths, or matching the ends of two-piece racks to generate ongoing lengths longer than stock.
Gear racks attribute industry regular fourteen-1/2° stress angle for purposes where manage of backlash is crucial (will not function with 20° spurs). Precision machining for small heart distance variation and enhanced concentricity of mating spur gears. These equipment racks can be modified for distinct applications such as drilling and tapping mounting holes, slicing to distinct lengths, or matching ends of two parts of rack to create a constant duration longer than stock.
