1PC Umupira, bizwi kandi nka PBV valve, ni ubwoko bwa valve yagenewe kugenzura imigendekere yamazi mumiyoboro. Ikoreshwa cyane mu nganda zitandukanye, zirimo peteroli na gaze, imiti, no gutunganya amazi.
Ikintu kimwe cyingenzi kiranga 1PC Ball Valves nu rutonde rwa WOG 2000. WOG isobanura "Umuvuduko Ukora, Amavuta, Gazi," kandi yerekana umuvuduko ntarengwa aho valve ishobora gukora neza. A.2000 WOG Irashobora kwihanganira imikazo igera kuri pound 2000 kuri santimetero kare, ikemeza imikorere yizewe no mubihe bikabije.
Iyi mibande iroroshye gukora, hamwe na lever yoroshye cyangwa ikiganza kizunguruka umupira imbere mumubiri wa valve. Iyo ikiganza kiri mumwanya ufunguye, umupira urazunguruka kugirango wemererwe gutemba, kandi mugihe ufunze, bihagarika gutemba burundu.
