Inqubo yokukhiqiza ye-valve yebhola yensimbi engagqwali iwukucubungula impahla yensimbi engagqwali ibe yisimo sebhola, bese wengeza umzila owuketshezi olinganayo phakathi kwebhola ukuze wakhe umzimba webhola. Yakhiwe ngebhola lensimbi engagqwali, umzimba wensimbi engagqwali kanye nesiqu se-valve yensimbi engagqwali, isibambo sensimbi noma isibambo sensimbi engagqwali.
Izinto ze-valve yebhola yensimbi engagqwali ngokuvamile zenziwe ngensimbi engagqwali engu-201 esezingeni eliphezulu, enokumelana nokugqwala okuhle kakhulu nokumelana nokushisa okuphezulu, ngakho-ke ifaneleka ezindaweni ezahlukahlukene ezinokhahlo. Njengokusetshenziswa kwamapayipi amanzi, amakhemikhali, amafutha, igesi yemvelo, imithi, ukudla, iphepha kanye neminye imikhakha. Ukumelana nokugqwala kwayo okuhle kakhulu, ukumelana nezinga lokushisa eliphezulu nokusebenza okulula kuyenza ibe ngelinye lamavalvu abalulekile ohlelweni lwamapayipi. Kungakhathaliseki ukuthi izimo zemvelo ezinzima noma izinga lokushisa eliphezulu kanye nezindawo zokusebenza ezinomfutho ophezulu, ama-valve ebhola ensimbi engagqwali angakwazi ukulawula ngokunembile nangokuthembekile ukuhamba kwemidiya futhi anqume amapayipi.
