I-PVC (i-polyvinyl chloride) kunye ne-UPVC (ipolyvinyl chloride engafakwanga plastiki) zizixhobo ezisetyenziswa ngokubanzi xa kusenziwa izifakelo ezahlukeneyo zevalvu.

Ezi zixhobo zaziwa ngokuqina kwazo, ukuxhathisa umhlwa, kunye nokufikeleleka kwazo, nto leyo ezenza zibe lukhetho oludumileyo kuluhlu olubanzi lwezicelo. Olunye uhlobo lokufakwa kwevalve oluqhele ukwenziwa ngePVC okanye iUPVC yivalve yebhabhathane.

Umgaqo wevalve yebhabhathane yePVC usekwe kuyilo olulula kodwa olusebenzayo. I-valve iqukethe i-disc, efakwe kwi-shaft ejikelezayo. Xa i-valve isendaweni evaliweyo, i-disc i-perpendicular ukuhamba kwamanzi, ngokuyithintela ngokufanelekileyo. Xa i-valve ivuliwe, i-disc ijikeleza ngokuhambelana nokuhamba, ivumela ulwelo ukuba ludlule.

Ukusetyenziswa kwe-PVC okanye i-UPVC ekwakhiweni kweevalve zebhabhathane inika iingenelo ezininzi. Ezi zixhobo zikhaphukhaphu, zenza iivalve zibe lula ukuphatha nokuzifaka. Kananjalo ziyakwazi ukumelana nomhlwa, zizenza zilungele ukusetyenziswa kwiindawo ezahlukeneyo, kubandakanywa nezo zichaphazeleka kwimichiza okanye iimeko zemozulu ezinzima. Ukongeza, i-PVC kunye ne-UPVC azinatyhefu kwaye zikhuselekile ukuba zisetyenziswe kwizicelo ezibandakanya amanzi okusela okanye ukulungiswa kokutya.

Umphezulu ogudileyo wangaphakathi wePVC kunye ne-UPVC butterfly valves kunciphisa ukuchasana nokuhamba, ukunciphisa ukuhla koxinzelelo kunye nokusetyenziswa kwamandla. Oku kubenza ukhetho olufanelekileyo lokulawula ukuhamba kwamanzi kwinkqubo. Ngaphaya koko, ezi zixhobo zigcinwa ziphantsi, zifuna ukugcinwa okuncinci kubomi babo.

Iivalvu zebhabhathane zePVC kunye ne-UPVC ziqhele ukusetyenziswa kumashishini afana nokucocwa kwamanzi, ukunkcenkceshela, ukusetyenzwa kweekhemikhali, kunye neenkqubo zeHVAC. Ukuguquguquka kwazo kunye nokusebenza kakuhle kweendleko kubenza ukhetho oludumileyo lokulawula ukuhamba kwamanzi, umoya, kunye nolunye ulwelo kuluhlu olubanzi lwezicelo.

Ukuqukumbela, umgaqo we-PVC butterfly valve usekelwe ekujikelezeni kwediski ukulawula ukuhamba kwamanzi. Ukusetyenziswa kwezixhobo zePVC kunye ne-UPVC ekwakhiweni kwezi zivalo zibonelela ngeenzuzo ezininzi, kubandakanya ukuqina, ukuxhathisa umhlwa, kunye nokusebenza kakuhle. Ezi mpawu zenza i-PVC kunye ne-UPVC i-butterfly valves ibe sisisombululo esithembekileyo nesingabizi kakhulu sokulawula ulwelo kwiindawo ezahlukeneyo zoshishino kunye nezorhwebo.
