Valavu ya pneumatic ndi valavu yowongolera yokha yomwe imayendetsedwa ndi mphamvu ya pneumatic. Mfundo yake yogwirira ntchito imachokera pa pneumatic force amplification mfundo ndi mfundo yodula. Kuthamanga kwa mpweya kumagwira ntchito pa pneumatic actuator, kupanikizika kwa mpweya kumakulitsidwa kudzera mu mphamvu yowonjezera, motero imayendetsa valve kuti itsegule kapena kutseka.

Valve yowunikira, monga valve yodziwika bwino ya mapaipi, yakhala ikugwiritsidwa ntchito kwambiri m'makina a mapaipi a mafakitale chifukwa cha kapangidwe kake kakang'ono, kuika mosavuta, kusindikiza bwino, ndi zina zotero.

Popanga mafakitale, ma valve, monga zida zowongolera pamapaipi amadzimadzi, amagwira ntchito yofunika kwambiri pakuwonetsetsa kuti dongosololi likuyenda bwino. Mavavu amatha kuwongolera kuyenda, kupanikizika ndi kuyenda kwa sing'anga molingana ndi momwe amagwirira ntchito. M'zaka zaposachedwa, ndikusintha kosalekeza kwa makina opanga mafakitale, zofunikira pakuchita ma valve zakwera kwambiri. Monga mtundu watsopano wa ma valve, ma valve oyandama achitsulo pang'onopang'ono akopa chidwi cha msika chifukwa cha ntchito yawo yapamwamba. Nkhaniyi ifananiza ndi kuphunzira mavavu oyandama achitsulo ndi mavavu achikhalidwe, kusanthula zabwino ndi zoyipa zawo, ndikupereka maupangiri aukadaulo.
