I-valve yebhola enezicucu ezintathu iqukethe indlu ye-valve eziyizicucu ezintathu, futhi umzimba ophakathi kanye nebhola le-valve zibanjwa kusuka emaphethelweni omabili ngezibopho ezine ezinde. Ibhola elinomgodi ophakathi lifakwa ngaphakathi komzimba we-valve, futhi umgodi onobubanzi obulingana nobubanzi bewashi uvulwa ebhola, futhi ibhola lingajikeleza esihlalweni sokuvaleka. Kukhona iringi ye-elastomer ohlangothini ngalunye lokuqondisa komshayo ukuze kufezekiswe ukuvaleka.

Indlela yokusebenza ye-valve yebhola enezicucu ezintathu ukujikeleza isiqu ukuze kuvulwe noma kuvinjwe i-valve. Ngokujikeleza ibhola ngo-90°, ungashintsha isiqondiso sokungena komgodi, ukuze wenze ushintsho lwe-valve yebhola. I-valve inezici zokushintsha okulula, usayizi omncane, ukuvaleka okuthembekile, njll. Isakhiwo sayo, indawo yokubeka uphawu, kanye nendawo eyindilinga kuvame ukuba sesimweni esivaliwe, okungelula ukuthi ihlaselwe umthombo.
