Ivalve yamatayara yinto encinci kakhulu kodwa ebaluleke kakhulu kwivili lesithuthi. Umgangatho wevalve unokuchaphazela ukhuseleko lokuqhuba. Ukuba itayara liyavuza, liya kwandisa ukusetyenziswa kwepetroli kunye nokwandisa umngcipheko wokuqhushumba kwetayara, ngaloo ndlela kuchaphazela ukhuseleko lwabakhweli emotweni.

Ngoko ukuthintela njani ukuba ivalve ingavuzi? Kubaluleke kakhulu ukubeka ingqalelo kumgangatho wemveliso xa kuthengwa i-valve. Kuyimfuneko ukuba kuqinisekiswe ukuba i-valve inokuqina kakuhle komoya ukuqinisekisa ukuba akukho kuvuza komoya okwenzekayo xa isithuthi sisebenza ngokuqhelekileyo.

Sincoma ukuba abasebenzisi bazame ukukhetha uphawu oluqinisekisiweyo lomgangatho okanye umthengisi xa kuthengwa ivalve. Nangona ivalve ibonakala ifana, abanye abavelisi bevalvu ababonelela ngamaxabiso aphantsi basenokungakwazi ukuqinisekisa ulawulo lomgangatho. Ukubonelela nge-100% yokuhlolwa kwe-valve yokuqina komoya.

Ukongezelela, kuyimfuneko ukuqinisekisa ukufakwa okuchanekileyo xa ufaka i-valve: i-phenomenon yokuvuza ye-valve esetyenziswayo ihambelana ngqo nokufakelwa okungalunganga. Ukuba kukho amabala amaninzi okanye ukungcola phakathi kwevalve kunye ne-valve core, nokuba ukutywinwa kulungile, kuya kukhokelela ekutywinweni kakubi ngexesha lokusetyenziswa. Ngoko ke, kucetyiswa ukuba uhlambulule isondo kunye nehabhu ngaphambi kokufaka i-valve.

Ekugqibeleni, nokuba i-valve yekhwalithi engcono kakhulu, kuba yenziwe ngokuyinhloko nge-rubber, ayinakuphepheka ukuba i-rubber iya kuhlahloka emva kwexesha elide lokusetyenziswa. Ivalve egugayo isenokubangela ukuba itayara ligqabhuke. Ngoko ke, kucetyiswa ukuba umsebenzisi atshintshe i-valve rhoqo emva kokusebenzisa isithuthi ixesha elide.
