Yendabukoamavalvu esango lommeseisebenza kahle ekulawuleni ukugeleza okuqondiswayo ngakunye, kodwa kuvame ukuba nengozi yokuvuza uma ibhekene nokugeleza okuqondiswayo okuqondiswayo. Ngokusekelwe ku-valve evamile yokunqamula ejwayelekile, ngocwaningo nentuthuko, umkhiqizo uthuthukisiwe, futhi umkhiqizo omusha "i-valve yepulaki yesivalo esithambile esinezindlela ezimbili" ukhuthazwe ukuqinisekisa ukuthi umphumela wokuvala ophumelelayo wokungavuki nhlobo ungatholakala kunoma iyiphi indlela yokugeleza.

Umklamo omusha ushintsha ukufakwa kwerabha yokuvala, uthatha indawo yomugqa werabha we-groove ku-ivalvu yesango le-sluiceumzimba onerabha enwebekayo, egoqwe emzimbeni wevalvu. Le nzuzo iwukuxazulula inkinga yokufakwa esikhundleni okunzima ngemva kokulahlekelwa ukuvalwa, uma ukulahlekelwa ukuvalwa kungashintshwa endaweni, ukufakwa okulula, ukuhlukaniswa okulula kanye nezinzuzo zokugcinwa, ukunciphisa umthelela ohlelweni lokukhiqiza.

Ngaphezu kwalokho, umucu werabha wokuvala owodwa ushintshwa ube umucu wokuvala okabili kanye nomucu wokuvala ongqimba oluphindwe kabili ukuze kuxazululwe izinkinga zokungacindezelwa ngokuphambene, kungakhathaliseki ukuthiivalvu yesango elijiyileUma ipuleti licindezelwe phambili noma ohlangothini lwengcindezi, ukuguquguquka kwerabha kungaxhunyaniswa eduze nepuleti yevalvu, ukuze kufezwe ukuvalwa okunezindlela ezimbili, kuthuthukiswe ukuvalwa, futhi kufezwe ukuvuza okungekho.

I-valve yethu entsha yesango lensimbi yokuvala ummese eqondiswe ohlangothini ngalunye ifanelekela amanzi ompompi, indle, imboni yokwelapha amanzi, isici esiyinhloko ukuzivala okuntantayo, ingcindezi eqondiswe ohlangothini ngalunye, ingafinyelela ukuvala ohlangothini ngalunye, ukuvala okuphezulu. Akulula ukuvuza, inesikhala esincane sokufaka, ingcindezi yokusebenza ephansi, akulula ukuqoqa udoti, isango lokucindezela okuphezulu alinawo umsindo, isiteshi esiqondile, ukumelana nokugeleza okuncane, akukho mehluko wokulahlekelwa yingcindezi, lapho isango livaliwe, ingcindezi ephakathi ethembekile isunduza ingcindezi yesango kolunye uhlangothi lwesihlalo se-valve yesango lokuvala ukuqinisekisa indawo yokuvala. Lokhu kusungula akugcini nje ngokuthuthukisa kakhulu ukuqina nokuthembeka kwe-valve, kodwa futhi kunciphisa kakhulu ukulahleka kwamandla kanye nokungcola kwemvelo okubangelwa ukuvuza. Ngemva kokuvela kwama-valve esango lokuvala ummese eqondiswe ohlangothini ngalunye, inani elikhulu lama-valve ajwayelekile anqunyiwe athathelwe indawo yiwo.
