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 zithandwe kakhulu ukuqina kwazo. Izinto ezisetshenziswayo azikwazi ukugqwala futhi azinakekelo, ngakho-ke 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. Lapho 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.
