Izihlalo zeTungsten carbide kunye neeVave zisetyenziswa kwiifayile ezahlukeneyo zeoyile kunye negesi, iivalvu zeoyile, ishishini lemichiza yamalahle. Kwimeko yexesha elide kunye nexesha elinzima lokusebenza, i-tungsten carbide valve iyona nto ingcono kakhulu. Ngelo xesha, i-valve ye-tungsten ye-carbide kunye nesihlalo sineenzuzo ezilandelayo: ingxolo ephantsi kunye nokumelana okuphezulu; ubunzima obuphezulu, amandla acinezelayo aphezulu; Uzinzo oluhle lweekhemikhali kunye nokuqina kwempembelelo ephantsi; i-coefficient yokwandisa okuphantsi; ukuqhuba ubushushu kunye nokuqhutywa kombane.
