I-1.Ukuxhathisa ulwelo kuncinci kwaye i-coefficient yayo yokudonsa ilingana nobude obufanayo.
I-2.Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula.
I-3.I-Close kwaye inokwethenjelwa, into yokutywinwa kwe-valve yebhola isetyenziswe ngokubanzi kwiplastiki kunye nokutywinwa, kwaye isetyenziswa ngokubanzi kwi-vacuum system.
I-4.Easy ukusebenza, vula kwaye uvale ngokukhawuleza, ukusuka ekuvuleni ukuvala ukujikeleza nje i-90 °, kunenzuzo kulawulo olude.
I-5.Easy ukuyigcina, isakhiwo se-valve yebhola silula, ikhonkco lokutywina lisebenza ngokuqhelekileyo, ukuchithwa kunye nokutshintshwa kukulungele ngakumbi.
6.Umphezulu wokutywina webhola kunye nesihlalo sahluliwe ukusuka kwindawo evulekile ngokupheleleyo okanye evaliweyo.Xa i-medium idlulisiwe, indawo yokutywina yevalve ayiyi kutshatyalaliswa.
7.Uluhlu olubanzi lwezicelo, ukusuka kwincinci ukuya kwiimilimitha ezininzi, ezinkulu ukuya kwiimitha ezininzi, ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu lunokusetyenziswa.
Ivalve yebhola yentsimbi eneziqwenga ezintathu luhlobo olutsha lwevalve yebhola.Ineenzuzo ezithile ezikhethekileyo kwisakhiwo sayo, njengokungabikho kongquzulwano kwiswitshi, akukho lula ukunxiba, kunye nokuvula okuncinci kunye nomzuzu wokuvala.Oku kunciphisa ukucaciswa kwe-actuator ehambelanayo.Nge-actuator yombane ejikelezayo emininzi ilungiswe kwaye inqunyulwe ngokuqinileyo.Isetyenziswa kakhulu kwi-oyile, imboni yeekhemikhali, ukubonelela ngamanzi asezidolophini kunye nokukhupha amanzi, njl.
