1. Vula kwaye uvale ngaphandle kokungqubuzana.Lo msebenzi usombulula ngokupheleleyo ingxaki yokuba i-valve yendabuko ichaphazelekayo yingxabano phakathi kwendawo yokutywinwa kunye nokutywinwa.
2. Isakhiwo sejacket.I-valve efakwe kumbhobho inokujongwa kwaye ilungiswe ngokuthe ngqo.Inokunciphisa ngokufanelekileyo ukupaka kunye nokunciphisa iindleko zokuvelisa.
3. Uyilo lwesihlalo esinye.Iphelisa ingxaki yokuba i-cavity ephakathi yevalve ichaphazeleka ngoxinzelelo olungaqhelekanga.
4. Uyilo lwetorque ephantsi.Uyilo olukhethekileyo lolwakhiwo lwesiqu, kuphela ngesivalo esincinci sesandla esinokuvula nokuvala lula.
5. Isakhiwo sokutywinwa kwe-Wedge.Ivalve ngamandla omatshini abonelelwa sisikhondo kwaye i-wedge icinezelwe kwisihlalo kwaye itywinwe.Ukusebenza kokutywina kwevalve akuchatshazelwa kukutshintsha koxinzelelo lombhobho umahluko, kwaye ukusebenza kokutywina kuqinisekisiwe. phantsi kweemeko ezahlukeneyo zokusebenza.
6. Isakhiwo esizicoca ngokwaso somphezulu wokutywina.Xa ibhola ityekela isuka esihlalweni, amava okuhamba kombhobho ecaleni kwendawo yetywina ijonge ngokulinganayo ukuya kuma-360 °. kwakhona ihlamba izinto eziqokelelweyo kumphezulu wokutywina ukufezekisa iinjongo zokuzicoca.
