Imodi yokuvula i-valve: ukusetha kabusha ngesandla, ukugwema ingozi;
Imodi yokulondoloza: ukusebenza ngokuzinzile njengoba ivalvu ivuliwe noma ivaliwe (okungukuthi isimo esizinzile);
Isivinini sokuvala: nqamula ukunikezwa kwegesi phakathi kwe-1s;
Vala uma kwenzeka ukuzamazama okunamandla; i-valve ingakwazi ukuvala shaqa ngokuzenzakalelayo uma ushaka ngobudlova;
Ukukhululwa kokucindezela okuzimele: uma kwenzeka umehluko omkhulu wengcindezi phambi nangemuva kwe-valve, i-valve ingavulwa ngemva kokuvulwa kwe-valve yokukhululwa kwengcindezi. Ngakho, i-fuel gas ngeke ikhishwe emoyeni, isuse izinkinga zokuphepha ezifihliwe;
Siyakwamukela ukuze uchofoze inkinobho Yokubuza ukuze uthole amasampula amahhala!
