Isishwankathelo seMveliso
Ngokubanzi isetyenziswa kwiiseti zoqhagamshelo ezingadingi meko ithile okanye izinto ezithile, iivalvu zesango le-wedge zibonelela ngokutywinwa kwexesha elide kunye nokusebenza okuthembekileyo. Uyilo olukhethekileyo lwe-wedge lwevalvu luphakamisa umthwalo wokutywinwa, luvumela ukutywinwa okuqinileyo kwiimeko zoxinzelelo oluphezulu noluphantsi. Ixhaswa luthungelwano lokubonelela oludibeneyo kunye nobuchule obuqinileyo bokuvelisa, i-I-FLOW yeyona ndawo ilungileyo yeevalvu zesango le-wedge ezithengiswayo. Iivalvu zesango le-wedge ezenziwe ngokwezifiso ezivela kwi-I-FLOW zidlula kuyilo olunzima kunye novavanyo lomgangatho oluqinileyo ukuze kufezekiswe ukusebenza kwinqanaba elilandelayo.
