Maonekedwe osavuta (aang'ono komanso okongola, pogwiritsa ntchito aloyi ya aluminiyamu kupanga thupi la valve), kugwiritsa ntchito mphamvu zochepa, kukhazikika komanso kudalirika, nthawi yoyankha mwachangu (kuthamanga kwa 1ms), kuthamanga kwakukulu, zofunikira zochepa pakugwiritsa ntchito (zingagwiritsidwe ntchito fumbi, malo opanda mafuta omwe amagwiritsidwa ntchito), moyo wautali, etc.

Chifukwa cha zovuta zamkati mkati ndi zing'onozing'ono zambiri, kudziphatika ndi kusonkhana kungayambitse kutayika kwa ziwalo kapena kusonkhana kosayenera.Kudziphatika ndi kusonkhana sikuvomerezeka.4VA / AVB mndandanda udzaonekera bwino mu zomangamanga m'matauni, mafakitale a mankhwala, zitsulo, mafuta, mankhwala, chakudya, chitetezo cha chilengedwe ndi mafakitale ena.
