1.Ukumelana noketshezi kuncane futhi i-coefficient yayo yokudonsa ilingana nobude obufanayo.
I-2.Isakhiwo esilula, usayizi omncane kanye nesisindo esincane.
I-3.I-Close futhi inokwethenjelwa, into yokuvala i-valve yebhola isetshenziswa kakhulu epulasitiki nasekufakweni uphawu, futhi isetshenziswa kabanzi ohlelweni lwe-vacuum.
4.Kulula ukusebenza, vula futhi uvale ngokushesha, kusukela ekuvuleni kuya ekuvaleni nje ukushintshanisa 90 °, kunenzuzo isilawuli kude.
I-5.Kulula ukuyigcina, isakhiwo se-valve yebhola silula, indandatho yokuvala uphawu ngokuvamile iyasebenza, ukuhlakazeka nokushintshwa kulula kakhulu.
I-6.Indawo yokuvala yebhola nesihlalo ihlukaniswa nendawo evulekile noma evaliwe ngokugcwele.Lapho i-medium idluliswa, indawo yokuvala ye-valve ngeke iguguleke.
I-7.Uhlu olubanzi lwezinhlelo zokusebenza, kusukela ezincane kuya kumamilimitha amaningana, ezinkulu kuya kumamitha amaningana, kusukela ku-vacuum ephezulu kuya ekucindezelweni okuphezulu kungasetshenziswa.
I-valve yensimbi engenasici eneziqephu ezintathu iwuhlobo olusha lwe-valve yebhola.Inezinzuzo ezithile ezihlukile ekwakhekeni kwayo, njengokuthi akukho ukungqubuzana kuswishi, akulula ukugqokwa, kanye nesikhashana esincane sokuvula nokuvala.Lokhu kunciphisa ukucaciswa kwe-actuator efanisiwe.Nge-actuator kagesi ezungezayo eminingi, okuphakathi kungaba ilungiswe futhi yasikwa ngokuqinile.Isetshenziswa kakhulu kuwoyela, embonini yamakhemikhali, ukuhlinzekwa kwamanzi asemadolobheni kanye ne-drainage, njll.
