Simungadziwe zambiri za ma valve otetezera, koma zikafika pakudzaza (kusefukira) ma valve, ma valve odzaza mafuta kapena mfuti zachiwiri, mukhoza kukhala ndi chidwi. Mavuto ena odziwika bwino a zofukula amayamba chifukwa cha kulephera kwa ma valve otetezera, monga kuthamanga pang'onopang'ono, kufooka, kuphulika kwa chitoliro kapena kuphulika kwa chitoliro cha hydraulic, kupindika kwa silinda ndi zina zotero. Popanda zonena zambiri, m'bale wokumba wotsatira adzakupatsani chidziwitso chatsatanetsatane cha yankho la valavu yachitetezo ndi kulephera kwake, ndikukhulupirira kuti mudzakhala odzala ndi zokolola.
Valve yothandizira imayikidwa pa valavu yaikulu yolamulira (wogawa) pambali pa tsinde logwira ntchito. Mawonekedwe, valavu yothandizira ndi yozungulira komanso yofanana kwambiri ndi valavu yayikulu yothandizira. Kusiyanitsa ndiko kusintha kwa ulusi pamwamba. Valavu yotetezera imakhala ndi ulusi umodzi ndipo valavu yayikulu yothandizira imakhala ndi ulusi iwiri. Pamalo opanikizika, kupanikizika kwa valve yotetezera ndipamwamba kuposa kupanikizika kwa valve yaikulu yothandizira.
Muzochitika zachilendo, valavu yachitetezo sichigwira nawo ntchito, kotero kuti kupanikizika kwa valve yachitetezo ndikwapadera ndipo sikungayesedwe mwachindunji ndi chida. Kupsyinjika kwa valve yaikulu yothandizira kumayenera kuwonjezereka pasadakhale ndipo kungayesedwe pokhapokha ngati kuli kwakukulu kuposa kupanikizika kwa valve yotetezera.
