Ivalvu isetshenziselwa ukuvula nokuvala ipayipi, ukulawula isiqondiso sokugeleza, ukulungisa nokulawula imingcele yendawo yokudlulisa (izinga lokushisa, ukucindezela nokugeleza) izesekeli zamapayipi. Ngokomsebenzi wayo, ingahlukaniswa nge-valve yokuvala, i-valve yokuhlola, i-valve yokulawula, njll.

Ivalvu iyingxenye yokulawula kusistimu yokudlulisa uketshezi, enemisebenzi yokunqamula, ukulawula, ukuphambukisa, ukuvimbela okuphikisanayo, ukuqiniswa kwengcindezi, ukuphambukisa noma ukukhululeka kokuchichima, njll. Amavavu ezinhlelo zokulawula uketshezi asukela kumavalvu embulunga alula kuya kulawo asetshenziswa ezinhlelweni ezishintshayo eziyinkimbinkimbi kakhulu.

Amavalvu angasetshenziswa ukulawula ukugeleza komoya, amanzi, isitimu, imidiya egqwalayo, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe nezinye izinhlobo zoketshezi. Amavalvu ngokuya ngezinto ezibonakalayo nawo ahlukaniswe abe ama-valve ensimbi, ama-valve ensimbi, ama-valve ensimbi engagqwali (201, 304, 316, njll.), ama-valve ensimbi e-chromium molybdenum, ama-valve ensimbi e-chromium molybdenum vanadium, ama-valve ensimbi anesigaba esiphindwe kabili, ama-valve epulasitiki, ama-valve angokwezifiso angajwayelekile.

I-valve ikusistimu yoketshezi, esetshenziselwa ukulawula isiqondiso soketshezi, ingcindezi, ukugeleza kwedivayisi, iwukwenza ipayipi nemishini phakathi (uketshezi, igesi, impushana) igeleze noma imise futhi ilawule ukugeleza kwedivayisi.

Ivalvu iyingxenye yokulawula yesistimu yokudlulisa uketshezi lwamapayipi, esetshenziselwa ukushintsha ingxenye yephaseji kanye nendawo yokugeleza okumaphakathi, ngokuphambukisa, ukunqamula, ukugoqa, isheke, ukuphambukisa noma imisebenzi yokukhulula ingcindezi. I-valve esetshenziselwa ukulawula uketshezi, kusukela ku-valve yembulunga elula kakhulu kuya ohlelweni lokulawula oluzenzakalelayo oluyinkimbinkimbi kakhulu olusetshenziswa ezinhlobonhlobo zamavalvu, ukuhlukahluka kwawo kanye nokucaciswa kwawo, usayizi ovamile wevalvu kusukela ku-valve yensimbi encane kakhulu kuya kusayizi wevalvu yepayipi yezimboni efika ku-10m. Ingasetshenziswa ukulawula amanzi, umusi, uwoyela, igesi, udaka, izinhlobonhlobo zemithombo yezindaba ezonakalisayo, insimbi ewuketshezi kanye noketshezi olukhipha imisebe nezinye izinhlobo zokugeleza koketshezi, ingcindezi yokusebenza kwe-valve ingaba isuka ku-0.0013MPa iye ku-1000MPa yokucindezela okuphezulu kakhulu, izinga lokushisa lokusebenza lingaba C-270 ℃ lokushisa eliphansi kakhulu kuya ku-1430.

I-valve ingalawulwa ngezindlela ezihlukahlukene zokudlulisela, njenge-manual, kagesi, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic, i-electro-hydraulic, i-electro-hydraulic, i-gas-hydraulic, i-spur gear, i-bevel gear drive; Ngokucindezela, izinga lokushisa noma olunye uhlobo ngaphansi kwesenzo sezimpawu zenzwa, isenzo, ngokuya ngemfuneko yokubhukha noma kungancikile kumasignali wezinzwa ukuze kube lula ukuvula noma ukuvala shaqa, kuncike kudrayivu noma kumshini ozenzakalelayo okwenza i-valve yokuvula nokuvala yokuphakamisa, ukushelela, indawo noma ukunyakaza okuzungezayo, ukuze ushintshe usayizi wechweba ukuze ukwazi ukubona umsebenzi wokulawula.
