Ngokuvamile asetshenziselwa ukwakheka kwezwe, ama-valve ebhola e-PVC akuvumela ukuthi uvule futhi uvale ukugeleza koketshezi ngokushesha, kuyilapho udala uphawu olungangeni manzi. Lawa ma-valve athile asebenza kahle kumachibi, amalabhorethri, izimboni zokudla neziphuzo, ukwelashwa kwamanzi, izicelo zesayensi yempilo kanye nezicelo zamakhemikhali. Lawa ma-valve anebhola ngaphakathi elizungeza i-axis ye-90-degree. Imbobo phakathi nendawo yebhola ivumela amanzi ukuthi ageleze ngokukhululekile lapho i-valve isendaweni "evuliwe", kuyilapho imisa ukugeleza ngokuphelele lapho i-valve isendaweni "yokucisha".
Ama-valve ebhola angenziwa ngezinto ezihlukahlukene, kodwa i-PVC iyona ekhethwa kakhulu. Okwenza lezi zidume kakhulu ukuqina kwazo. Izinto ezisetshenziswayo azikwazi ukugqwala futhi azinakekelo, ngakho zingasetshenziswa ezinhlelweni zangaphandle lapho zingadingeki khona njalo, kodwa uma zidingeka kubalulekile ukuthi zisebenze kahle. Angasetshenziswa futhi ekuxubeni amakhemikhali, lapho ukugqwala kungaba yinkinga enkulu. Ukumelana nokucindezela okuphezulu kwe-PVC nakho kuyenza idume ezinhlelweni zokusebenza lapho uketshezi lugeleza ngomfutho omkhulu. Uma i-valve ivuliwe, kuba nokwehla okuncane kokucindezela ngenxa yokuthi imbobo yebhola icishe ifane ngosayizi nembobo yepayipi.
Ama-valve ebhola e-PVC afika ezinhlobonhlobo zamadayamitha. Siphatha ama-valve ngosayizi ukusuka ku-1/2 intshi kuya ku-6 amayintshi, kodwa izinketho ezinkulu zingatholakala uma kudingeka. Siphethe inyunyana ye-saking yeqiniso, inyunyana yangempela kanye nama-valve ebhola ahlangene ukuze sihlangabezane nezidingo eziningi. Ama-valve ezinyunyana zangempela athandwa kakhulu ngoba avumela ukukhishwa kwengxenye yenkampani ye-valve, ngaphandle kokukhipha yonke i-valve ohlelweni, ngakho ukulungisa nokugcinwa kulula. Konke kufaka ukuqina kwe-PVC ukukunikeza iminyaka eminingi yokusebenzisa.
