I-valve icandelo lokulawula kwinkqubo yokuhambisa umbane, kunye nemisebenzi yokunqunyulwa, ukulawulwa, ukuchithwa, ukuthintela i-countercurrent, ukuqina koxinzelelo, ukuguqulwa okanye ukugqithiswa kwengcinezelo yoxinzelelo.
Ivalve esetyenziswa kwinkqubo yokulawula ulwelo, ukusuka kweyona valve ilula yokumisa ukuya kweyona nkqubo yolawulo oluzenzekelayo entsonkothileyo, iintlobo zayo kunye neenkcukacha zahlukeneyo.Iivalvu zinokusetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo olunjengomoya, amanzi, umphunga, imithombo yeendaba eyonakalisayo, udaka, i-oyile, isinyithi solwelo kunye nemithombo yeendaba erediyo.Ngokwezinto eziphathekayo, ivalve iphinde yahlulwe ibe yintsimbi yentsimbi, ivalve yentsimbi, ivalve yentsimbi engenasici (201,304,316, njl.), chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, ivalve yentsimbi ephindwe kabini, iplastic valves, non -iivalvu ezisemgangathweni ezilungiselelweyo, njl.
