Iivalvu zebhabhathane zibonelela ngolawulo olukhaphukhaphu kunye nexabiso eliphantsi lokuhamba kwamanzi kwisitshizi somlilo kunye neenkqubo zombhobho omileyo.
Ivalve yebhabhathane ibeka yodwa okanye ilawule ukuhamba kolwelo kwiinkqubo zemibhobho. Ngelixa zinokusetyenziswa kunye nolwelo, iigesi, kunye ne-semi-solids, iivalvu zebhabhathane zokukhusela umlilo zisebenza njengeevalvu zokulawula ezivula okanye ezivala ukuhamba kwamanzi kwimibhobho ehambisa isitshizi somlilo okanye iinkqubo ze-standpipe.
Ivalve yebhabhathane yokukhusela umlilo iqala, imise, okanye icinezele ukuhamba kwamanzi ngokujikeleza kwediski yangaphakathi. Xa i-disc ijika ihambelana nokuhamba, amanzi angadlula ngokukhululekile. Jikelezisa i-disc 90 degrees, kunye nokuhamba kwamanzi kwi-system piping stops. Le diski ibhityileyo inokuhlala kwindlela yamanzi ngamaxesha onke ngaphandle kokucothisa kakhulu ukuhamba kwamanzi ngevalve.
Ukujikeleza kwediski kulawulwa livili lesandla. I-handwheel ijikeleza intonga okanye i-stem, ejika i-disc kwaye ijikeleze ngaxeshanye isalathisi sesimo - ngokuqhelekileyo iqhekeza elinemibala eqaqambileyo ephuma kwi-valve - ebonisa umqhubi wendlela idiski ejongene ngayo. Esi salathisi sivumela ukuqinisekiswa kokujonga nje ukuba i-valve ivuliwe okanye ivaliwe.
Isalathisi sesikhundla sidlala indima ebalulekileyo ekugcineni iinkqubo zokukhusela umlilo zisebenza. Iivalvu zebhabhathane zisebenza njengezivalo ezikwaziyo ukuvala amanzi ekutshiseni isitshizi okanye imibhobho emileyo okanye amacandelo azo. Izakhiwo zonke zinokushiywa zingenakuzikhusela xa ivalve yokulawula ishiywe ivaliwe. Isalathisi sesikhundla sinceda abaqeqeshi bomlilo kunye nabaphathi beziko babone i-valve evaliweyo kwaye bayivule ngokukhawuleza.
Uninzi lweevalvu zebhabhathane zokhuselo lomlilo zikwabandakanya iiswitshi ze-tamper ze-elektroniki ezinxibelelana nephaneli yolawulo kwaye zithumele i-alam xa idiski yevalve ijikeleza. Ngokuqhelekileyo, zibandakanya iiswitshi ezimbini ze-tamper: enye yokudibanisa kwipaneli yokulawula umlilo kunye nenye yokudibanisa kwisixhobo esincedisayo, njengentsimbi okanye uphondo.
