API 6D -palloventtiili

Worm wheel type all-welded ball valve is suitable for cutting or connecting the medium in thepipeline of petroleum, chemical industry, thermal power station and other working conditions Class150 ~ 300Lb and operating temperature -29 ~ 200c.Applicable medium: petroleum, purified naturalgas, acid natural gas, gas, water and coal slurry, etc.Operating mode: worm gear drive, pneumatic, electric, gas - liquid linkage.

Structural characteristics

Wom wheel tvpe fuly welded balwale adots fixed balsitnucture. the uper and ower shat ofthe balare eouiped with bearnos.smal onerating orue.the bal of thi stnucture is fixeddoes not move afer compresjon, the desion has two sealng inas to provide enouoh pre-tiohtening force to ensure the seain, achieve double-sided forced seain,sealna peromance ismore relable.The machining processofthe sphere is tracked and detected by the advanced computerdetector sothe machining precision ofthe sphere is highAs the matenial of the wale bodyis the same asthat ofthe pipe, there wilbe no uneven stres or defomation due to the earthouake and vehicde pasina throuoh the qround. The seaing rina body is made of Pf matenalwith20%C(carbon), which ensures no leakage at all (0%).
