Trunnion Ball Valve Can Successfully decrease Operating Torque

Trunnion Ball Valve Can Successfully decrease Operating Torque

Trunnion ball valve is a fixed shaft ball valve type. The trunnion ball is loaded by the base of the valve body, and the bearing is arranged between the valve body and ear axis, and the trunnion ball rotates around its trunnion axis to realize the switch or cut of the flow. The dielectric force is borne by the trunnion bearing and can withstand the working force of the highest attainable MPa.

Each trunnion ball valve before the factory pass the 7MPa nitrogen force test, Trunnion ball vale and shell the valve seat in one minute no bubbles produced.

It solves the technical issues of complex structure,  bad sealing performance, big operating torque and little service life of existing ball valve.

Trunnion ball valve composition is compact, Trunnion ball valve the greatest flow design is largely used, high voltage frequent switch and so on all types of bad situations.

The trunnion ball valve contains the valve stem and the valve body is arranged in the valve body. A spherical spool is linked at one end of the stem, and a handle is linked at the other end of the stem, where the spherical and stem pool are provided with an ear shaft, and the diameter of the ear shaft is superior than the diameter of the stem. The valve body is offered with a locking structure at the link of the stem, and the spherical valve core is linked with a ball valve joint, card sleeve structure and Trunnion ball valve is arranged on the external end part of the valve valve joint. The utility model has the benefits of powerful structure, reasonable design, and top sealing performance, which can effectively decrease the opening torque and extend the service life.

The trunnion ball valve contains the valve body and the valve stem is arranged in the valve body. A spherical spool is linked at one end of the stem, and a handle is linked at the other end of the stem, wherein the spherical spool and stem are offered with an ear shaft, and the diameter of the ear shaft https://rizziovalvole.com/api-6d-trunnion-ball-valve/ is superior than the diameter of the stem and is less than cross-section diameter of the ball spool, the valve body is offered with a locking structure at the link of the stem, and the spherical valve core is linked with a ball valve joint, and a card sleeve structure is arranged on the exterior end part of the ball valve joint. The setting of the trunnion can decrease the operating torque and play an elastic buffering effect, and the formation of the locking structure and the clamping sleeve makes the ball valve more strong.

Powerful structure, reasonable design, top sealing performance, Trunnion ball valve can rightly decrease operating torque and extend service life.

This type of ball valve is largely used for sampling, gas filling device, and tool control device.
