A insimbi engagqwali ibhola valvewuhlobo lwevalvu esebenzisa idiski eyindilinga, eyaziwa ngokuthi yibhola, ukulawula ukugeleza koketshezi ngepayipi. Le valve iklanywe ngembobo emaphakathi nebhola, eqondana nokugeleza lapho i-valve ivuliwe, evumela uketshezi ukuba ludlule. Lapho i-valve ivaliwe, ibhola lizungeza endaweni lapho imbobo i-perpendicular to flow, ivimbele ngokuphumelelayo.
Ama-valve ebhola ensimbi ahlonishwa kakhulu ngenxa yokuqina kwawo kanye nokumelana nokugqwala, okuwenza alungele ukusetshenziswa okubanzi, okuhlanganisa amanzi, uwoyela, igesi, nokucutshungulwa kwamakhemikhali. Ukusetshenziswa kwensimbi engagqwali ekwakhiweni kwazo kuqinisekisa ukuthi lawa ma-valve angakwazi ukumelana nezindawo ezinokhahlo futhi agcine ubuqotho bawo ngokuhamba kwesikhathi.
Njengomkhiqizi ohamba phambili wamavalvu ebhola, inkampani yamavalvu e-NSW igxile ekukhiqizeni amavalvu ebhola ensimbi engagqwali esezingeni eliphezulu ahlangabezana nezindinganiso zomkhakha. Laba bakhiqizi basebenzisa ubuchwepheshe obuthuthukisiwe nokuhlola okuqinile ukuze baqinisekise ukuthi imikhiqizo yabo ithembekile futhi isebenza kahle. Inqubo yokukhiqiza ngokuvamile ihilela ukunemba kwemishini kanye nezinyathelo zokulawula ikhwalithi ukuze kuqinisekiswe ukuthi i-valve ngayinye isebenza kahle ngaphansi kwezimo ezihlukahlukene.
Ngaphezu kokwakhiwa kwawo okuqinile, ama-valve ebhola ensimbi engenasici anikeza izinzuzo eziningana, kuhlanganise nezidingo eziphansi ze-torque yokusebenza, ukwehla kwengcindezi encane, kanye nekhono lokusingatha amazinga aphezulu okugeleza. Kulula futhi ukuzinakekela, ngemiklamo eminingi enesakhiwo esilula esivumela ukuqaqa nokuhlanza ngokushesha.
Kafushane, i-valve yebhola yensimbi engagqwali iyisici esibalulekile ezinhlelweni eziningi zezimboni, ehlinzeka ngokulawula ukugeleza okuthembekile nokuqina. Ngobuchwepheshe babakhiqizi bamavalvu ebhola abahlonishwayo, lawa mavalvu ayaqhubeka nokuvela, ahlanganisa imiklamo emisha nezinto zokwakha ukuhlangabezana nezidingo zezimboni zesimanje.
