Valavu yowunikira imadziwikanso kuti valavu yoyendera m'mbuyo, valavu yowunikira, valavu yowunikira kumbuyo ndi valavu yolowera mbali imodzi. Mavavu awa amatsegulidwa ndi kutsekedwa okha ndi kuyenda kwa cholumikiziracho chomwe chili mu payipi, chomwe ndi cha valavu yodziwikiratu. Yogwiritsidwa ntchito mu dongosolo la mapaipi, ntchito yake yayikulu ndikuletsa kuyenda kwapakati, kuletsa pampu ndi kuyendetsa mota kubwerera m'mbuyo, komanso kutulutsa kwa chotengera. Ingagwiritsidwenso ntchito kupereka mizere ya machitidwe othandizira momwe kuthamanga kungakwerere kupitirira kuthamanga kwa dongosolo. Itha kugawidwa m'magulu awiri: mtundu wa swing (wozungulira malinga ndi pakati pa mphamvu yokoka) ndi mtundu wokweza (woyenda motsatira mzere).
Ma valve oyezera opindika angagwiritsidwenso ntchito kupereka mizere yomwe mphamvu ingakwere kupita ku dongosolo lothandizira lomwe limaposa mphamvu ya dongosolo. Likhoza kugawidwa m'magulu awiri: mtundu wa swing ndi mtundu wa lift. Mtundu wa swing ndi woyenera mafakitale amafuta, mankhwala, mankhwala, feteleza, magetsi ndi zina zomwe zimagwiritsidwa ntchito pa mapaipi okhala ndi mphamvu ya PN1.6 ~ 16.0mpa ndi kutentha kwa ntchito -29 ~ + 550 °.
