I-PVC (i-Polyvinyl Chloride) inikezela ngezinto ezikwazi ukumelana nokuguguleka nokugqwala ezifanele ukusetshenziswa okuhlukahlukene kwezindawo zokuhlala, ezohwebo nezimboni.I-CPVC (i-Chlorinated Polyvinyl Chloride) iwuhlobo lwe-PVC evumelana nezimo futhi ekwazi ukumelana namazinga okushisa aphakeme.Kokubili i-PVC ne-CPVC yizinto ezingasindi kodwa ezimangelengele ezivikela ukugqwala, okuzenza zilungele ukusetshenziswa ezindaweni eziningi zamanzi.
Ama-valve enziwe nge-PCV kanye ne-CPVC avame ukusetshenziselwa inqubo yamakhemikhali, amanzi aphuzwayo, ukuchelela, ukwelashwa kwamanzi kanye namanzi angcolile, ukuhlelwa kwendawo, ichibi, ichibi, ukuphepha komlilo, ukuphisa, nezinye izinhlelo zokusebenza zokudla nesiphuzo.Ziyisixazululo esihle sezindleko eziphansi sezidingo eziningi zokulawula ukugeleza
