Ivalvu yokudlula yomjikelezo ongenamkhawuloiyisethi yezingxenye ezimfushane ezingavulwa futhi zivalwe izikhathi eziningi, ngokuvamile ezifakwa ezinhlanganisela zamathuluzi okumba akhethekile njengokuma kwawo, ukusheshisa, nokugawulwa kwemithi ngenkathi kubholwa, okungavula futhi kuvalwe izimbobo zokudlula ngesikhathi ngokwemibandela ye-downhole yokusebenza okukhethekile, ukuthuthukisa ukusebenza kwezinhlanganisela zamathuluzi okumba akhethekile, ukusiza ukuthuthukisa ukusebenza kahle kokukhiqiza, nokunciphisa izingozi zokulawula imithombo.
Emisebenzini ye-downhole, njengokuxhuma ukuvuza, umjovo we-asidi, ukusebenza, kanye nokuqedwa, ukwenza kusebenze okuningi kwevalvu yokudlula kungavikela inhlanganisela yamathuluzi okubhoboza aphansi.Ivalvu yokudlula yomjikelezo ongenamkhawuloingasiza ekuthuthukiseni ukusebenza kahle kokusika ekusebenzeni kokunwetshwa kwamehlo, ithuthukise izinga lokugeleza kwe-annular emthonjeni ovundlile kanye nokumba umthombo oqondisayo, futhi ithuthukise ikhono lokuhlanza ohlangothini olungezansi lodonga lomthombo.
Izinzuzo eziyinhloko zezobuchwepheshe zei-valve yokudlula umjikelezo ongenamkhawulozimi kanje:
(1) Ingakwazi ukubona imisebenzi ekhethekile njengokungabholi nokuxhuma, futhi inciphise umjikelezo wokumba;
(2) Ivalvu yokudlula ivala ngokuzenzakalelayo lapho iphampu imisiwe ukuze kugwenywe umphumela wepayipi elimise okuka-U noma izinkinga zokulawula umthombo;
(3) Ayinqunyelwe imbobo yamanzi yamathuluzi emigodi ephansi, amathuluzi, nezinsimbi zokubhoboza, futhi ingakwazi ukubona indawo enkulu yokuwasha kahle;
(4) Ingakwazi ukususa ngokuphumelelayo umbhede we-rock chip wemithombo eqondisayo kanye nemithombo evundlile;
(5) Ingakwazi ukuvikela ngempumelelo amathuluzi okukhipha amanzi kanye namathuluzi okumba amandla
