Umsebenzi wobuciko: Izinhlobo eziyisishiyagalombili ezijwayelekile zamavalvu, enziwe lula kakhulu.Ukhiye wombala: ingxenye empunga yipayipi okugeleza uketshezi;ingxenye ebomvu i-valve nesibambo sayo noma isilawuli;imicibisholo eluhlaza okwesibhakabhaka ibonisa ukuthi i-valve ihamba kanjani noma ijika;futhi umugqa ophuzi ukhombisa ukuthi uketshezi luhamba ngayiphi indlela lapho i-valve ivuliwe.

Izinhlobo eziningi ezahlukene zamavalvu zonke zinamagama ahlukene.Okuvame kakhulu uvemvane, iqhude noma ipulaki, isango, imbulunga, inaliti, i-poppet, ne-spool:

• Ibhola: Ku-valve yebhola, i-sphere egobile (ibhola) ihlala iqinile ngaphakathi kwepayipi, ivimbe ngokuphelele ukugeleza koketshezi.Uma uphendula isibambo, lenza ibhola lijike libe ngamadigri angamashumi ayisishiyagalolunye, okuvumela uketshezi ukuthi lugeleze phakathi nalo.

• Isango noma i-sluice: Amavalvu esango avula futhi avale amapayipi ngokwehlisa amasango ensimbi awele kuwo.Amavalvu amaningi alolu hlobo aklanyelwe ukuthi avuleke ngokugcwele noma avaleke ngokugcwele futhi angase angasebenzi kahle uma evuleke ingxenye.Amapayipi okuhambisa amanzi asebenzisa ama-valve afana nalawa.

• Imbulunga: Ompompi bamanzi (ompompi) bayizibonelo zamavalvu embulunga.Uma uphendulela isibambo, ugoqa ivalve phezulu noma phansi futhi lokhu kuvumela amanzi acindezelwe ukuthi agelezele phezulu ngepayipi aphume ngespout ngezansi.Ngokungafani nesango noma i-sluice, i-valve efana nale ingasethwa ukuze ivumele uketshezi oluningi noma oluncane kuyo.
