Ngokuvamile asetshenziswa ekubukeni komhlaba, 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.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.
