1.Fluid resistance ndi yaying'ono, ndipo coefficient yake yotsutsa ndi yofanana ndi gawo la chitoliro la kutalika komweko.
2.Mapangidwe osavuta, voliyumu yaying'ono, kulemera kopepuka.
3.Yolimba komanso yodalirika, valavu yosindikizira ya mpira pamwamba pa zinthu zomwe zimagwiritsidwa ntchito kwambiri pulasitiki, kusindikiza bwino, mu makina otsekemera akhala akugwiritsidwa ntchito kwambiri.
4.Easy kugwira ntchito, mwamsanga kutsegula ndi kutseka, kuchokera kutseguka kwathunthu mpaka kutseka kwathunthu mpaka kuzungulira kwa 90 °, kosavuta kulamulira kutali.
5.Kukonza kosavuta, mawonekedwe a valve a mpira ndi ophweka, mphete yosindikizira imakhala yogwira ntchito, kusokoneza ndi kusinthanitsa kumakhala kosavuta.
6.Kutsegula kwathunthu kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando amasiyanitsidwa ndi sing'anga, ndipo sing'angayo sichidzayambitsa kuwonongeka kwa chisindikizo cha valve pamene sing'anga ikudutsa.
Mbali yotseka ya valve ya mpira ndi mpira, mpirawo umazungulira kuzungulira pakati pa thupi la valve kuti akwaniritse cholinga chotsegula ndi kutseka, valavu ya mpira singagwiritsidwe ntchito pogwedeza;Mavavu a mpira amagwiritsidwa ntchito makamaka kudula, kugawa ndi kusintha kayendedwe ka mapaipi apakati.Vavu yamtunduwu iyenera kuyikidwa mopingasa mu chitoliro.Kusankha zipangizo zosiyanasiyana, akhoza ankalemekeza oyenera madzi, nthunzi, mafuta, asidi asidi, asidi acetic, makutidwe ndi okosijeni sing'anga, urea ndi TV zina, angagwiritsidwe ankagwiritsa ntchito papermaking, petrochemical, mankhwala, zitsulo, mphamvu yamagetsi, kuteteza chilengedwe, mafuta. , mafakitale opepuka ndi magawo ena a mafakitale a makina owongolera okha.
