Ukuqonda umgaqo wokusebenzela weValve yebhola, kubalulekile ukwazi iindawo ezi-5 eziphambili zexabiso kunye neentlobo ezi-2 zomsebenzi ezahlukeneyo. Izinto eziphambili ezi-5 zinokubonwa kumzobo we-vamic ye-2. I-valve stem (1) iqhagamshelwe kwibhola (4) kwaye isebenza ngesandla (ngombane okanye isebenza ngombane (ngombane okanye ngombane (ngombane okanye ngombane). Ibhola ixhaswa kwaye itywinwe sisihlalo se-valve yebhola (5) kunye nee-o-rings (2) ezijikeleze i-valve stem. Zonke zingaphakathi kwendlu yevalve (3). Ibhola inendawo yayo, njengoko ibonwa kwimbonakalo yecandelo.
