Ngokuqhelekileyo isetyenziswa kwi-landscaping, iivalvu zebhola ze-PVC zikuvumela ukuba uvule kwaye ucime ukuhamba kolwelo ngokukhawuleza, ngelixa udala itywina elingangeni manzi.Ezi zivalo ezithile zisebenza kakuhle kumachibi, iilabhoratri, amashishini okutya nesiselo, unyango lwamanzi, izicelo zesayensi yobomi kunye nokusetyenziswa kwemichiza.Ezi zivalo zinebhola ngaphakathi ezijikelezayo kwi-axis ye-90-degree.Umngxuma osembindini webhola uvumela amanzi ukuba ahambe ngokukhululekileyo xa ivalve ikwindawo “ekuyo”, ngelixa ivala ukuhamba ngokupheleleyo xa ivalve ikwimo “yokucima”.
Iivalve zebhola zingenziwa kwizinto ezahlukeneyo, kodwa i-PVC yeyona nto ikhethwa kakhulu.Yintoni eyenza ezi zinto zithandwa kakhulu kukuhlala kwazo.Izinto eziphathekayo azinamhlwa kwaye azinakugcinwa, ngoko zinokusetyenziswa kwizicelo zangaphandle apho zingafunwa rhoqo, kodwa xa zifuneka kubalulekile ukuba zisebenze ngokufanelekileyo.Zikwanokusetyenziselwa ukuxuba imichiza kwizicelo, apho ukubola kuya kuba yingxaki enkulu.Ukumelana noxinzelelo oluphezulu lwePVC kwakhona kuyenza idume kwizicelo apho ulwelo luqukuqela kuxinzelelo oluphezulu.Xa i-valve ivuliwe, kukho ukuhla okuncinci kuxinzelelo ngenxa yokuba i-port yebhola iphantse ifane nobukhulu kwi-port yombhobho.
Iivalvu zebhola zePVC ziza kuluhlu olubanzi lweedayamitha.Siphatha iivalvu ukusuka kwi-1/2 intshi ukuya kwi-intshi ezi-6, kodwa iinketho ezinkulu zinokufumaneka xa zifuneka.Sithwala umanyano lokwenyani, umanyano lokwenyani kunye neevalvu zebhola ezidityanisiweyo ukuhlangabezana noluhlu olubanzi lweemfuno.Iivalve zenyani zomanyano zithandwa kakhulu ngenxa yokuba zivumela ukukhutshwa kwesahlulo somthwali wevalve, ngaphandle kokuthatha i-valve yonke ngaphandle kwenkqubo, ngoko ukulungiswa nokugcinwa kulula.Zonke zibonisa ukuqina kwePVC ukukunika iminyaka emininzi yokusebenzisa.
