Kusanthula mwachidule kusiyana pakati pa valavu yoyendetsa mwachindunji ndi valve yoyendetsa ndege
Valve yochita mwachindunji ndi valavu yoyendetsa ndege imagawidwa molingana ndi mawonekedwe a valavu, kusiyana kwakukulu pakati pa ziwirizi ndikuti valavu yowonongeka imakhala ndi thupi limodzi lokha, ndipo valve yoyendetsa ndege imakhala ndi matupi awiri. Limodzi ndi thupi lalikulu la vavu ndipo linalo ndi gulu lothandizira la vavu. Pakati pawo, thupi lalikulu la valavu silosiyana kwambiri ndi mtundu wakuchita mwachindunji; Thupi lothandizira la valve limatchedwanso valavu yoyendetsa ndege, yomwe kwenikweni imakhala yofanana ndi valavu yaing'ono yothamanga molunjika.
M'malo mwake, kufanana pakati pa ma valve ochita molunjika ndi ma valve oyendetsa ndege ndikuwongolera kutsegula ndi kutseka kwapakati pa valve chifukwa cha kusalinganika kwa mphamvu yomwe ikugwira ntchito pamtima wa valve yaikulu (kuphatikizapo kuthamanga kwa mafuta ndi mphamvu ya masika, ndi zina zotero. ). Mtundu wachindunji wochitapo kanthu ndikuti mafuta oponderezedwa (mafuta) a dongosololi amagwira ntchito mwachindunji pamtima wa valavu yayikulu ndikuwongolera ndi mphamvu zina (monga mphamvu ya masika) kuti aziwongolera kutsegulira ndi kutseka kwapakati pa valve; Mtundu woyendetsa ndege umasintha mphamvu yomwe imagwira pamtima pa valavu yaikulu kupyolera mu kutsegula ndi kutseka kwa valavu yothandizira (pilot valve) valavu kuti athetse kutsegula ndi kutseka kwa chigawo chachikulu cha valve. Pachimake chachikulu cha valavu, chifukwa valavu yoyendetsa ndege imagwiritsa ntchito valavu yothandizira kuti isinthe momwe mphamvu ya valve ikuyendera, osati mwachindunji ndi mphamvu yolowera kuti isinthe mphamvu ya valve yaikulu, pali mwachindunji. "osalunjika" mogwirizana ndi mtundu wachindunji wa dzinalo
