The structure characteristics of pneumatic valve pneumatic eccentric hemisphere

open-close frictionless

this function completely solve the traditional pneumatic valves for sealing surface friction each other and affect the sealing problem.

jacket structure

the pneumatic valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost.

single pneumatic seat design

eliminates the pneumatic valve lumen medium because of abnormal pressure and problems affecting the safety of use.

low torque design

special structure design of the pneumatic valve stem, only with a small hand can easily open/close the pneumatic valve.

wedge seal structure

pneumatic pneumatic valve is eccentric hemisphere * pneumatic valve stem provides mechanical force, wedge pressure the ball into the pneumatic seat and seal, pneumatic valve's sealing is not affected by changes in the pipeline pressure difference, sealing performance under various condition have to * guarantee.

the self-cleaning structure of sealing surface

when sphere tilting away from the pneumatic valve seat, fluid in the pipeline along the sphere uniform sealing surface into ° through, not only eliminates the high velocity of pneumatic seat local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
