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

I-PVC (i-polyvinyl chloride) kunye ne-UPVC (i-polyvinyl chloride engaxutywanga) zizinto ezisetyenziswa ngokubanzi ekwenzeni izifakelo zevalve. Ezi zixhobo zeplastiki zaziwa ngokuhlala kwazo ixesha elide, ukuxhathisa umhlwa, kunye nokufikeleleka, nto leyo ezenza zibe lukhetho oludumileyo kwizicelo ezahlukeneyo, kubandakanya imibhobho yamanzi, ukunkcenkceshela, kunye neenkqubo zemizi-mveliso.

Olunye uhlobo oluqhelekileyo lokufakelwa kwevalve eyenziwe kwi-PVC okanye i-UPVC yivalve esezantsi ye-PVC, eyenzelwe ukulawula ukuhamba kwamanzi kunye nokuthintela ukubuya umva. Umgaqo osebenzayo wevalve esezantsi yePVC usekwe kwindlela elula kodwa esebenzayo. Xa ulwelo luqukuqela kwicala olifunayo, isivalo siyavuleka ukuze sivumele ukudlula kolwelo. Nangona kunjalo, xa kukho ukuguqulwa kokuhamba, i-valve ivala ngokuzenzekelayo ukuthintela ukubuya kolwelo.

Izinto eziphambili zevalve ephantsi ye-PVC ziquka umzimba wevalve, owenziwe ngokuqhelekileyo nge-PVC okanye i-UPVC, kunye nendlela yokutywina efana nerabha okanye i-silicone gasket. Xa uxinzelelo lolwelo luphezulu kwicala lokungena levalvu, lutyhala kwindlela yokutywina, nto leyo ebangela ukuba ivalve ivuleke kwaye ivumele ulwelo ukuba ludlule. Ngokuchaseneyo, xa uxinzelelo kwicala lokuphuma luba phezulu, indlela yokutywina icinezelwe kwisitulo sevalvu, ivale ngokufanelekileyo ukuphuma.

Ukusetyenziswa kwePVC okanye i-UPVC ekwakhiweni kweevalve ezisezantsi kunika iingenelo ezininzi. Ezi zixhobo zikhaphukhaphu, zenza iivalve zibe lula ukuphatha nokuzifaka. Ukongeza, i-PVC kunye ne-UPVC ziyaxhathisa ukubola, ukuthotywa kweekhemikhali, kunye nokukhula kwebhayoloji, izenza zilungele ukusetyenziswa kwiindawo ezininzi ezingqongileyo, kubandakanywa iimeko ezinobungozi kunye ne-abrasive.

Ngaphaya koko, iivalvu ezisezantsi ze-PVC kunye ne-UPVC ziindlela ezingabizi kakhulu kwiivalvu zentsimbi zemveli, ezibonelela ngokuthelekisa ukusebenza ngexabiso eliphantsi. Imiphezulu yazo yangaphakathi egudileyo ikwanciphisa ukuhla koxinzelelo kunye nesiphithiphithi, nto leyo enegalelo ekuhambeni kakuhle kolwelo.

Ukuqukumbela, i-PVC kunye ne-UPVC zizixhobo eziguquguqukayo zokwenza izifakelo zevalvu, kubandakanya iivalvu ezisezantsi. Umgaqo osebenzayo we-valve ephantsi ye-PVC isekelwe kwindlela ethembekileyo yoxinzelelo lwe-fluid ukulawula ukuhamba kunye nokukhusela umva. Ngokuhlala kwabo, ukuxhathisa ukubola, kunye nokusebenza kakuhle, i-PVC kunye ne-UPVC iivalvu ezisezantsi zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo zokulawula ulwelo.
