Ubungqina bokudubula obufihliweyo: akukho ntlantsi, izinzile kwaye inokuthenjwa;
Imodi yokuvula iValve: ukusetha kwakhona ngesandla, ukuphepha ingozi;
Imo yogcino: ukusebenza ngokuzinzileyo njengoko ivalve ivuliwe okanye ivaliwe (okt i-bi-stable state);
Isantya sokuvala: ukucima ukunikezelwa kwegesi ngaphakathi kwe-1s;
Ukuvalwa xa kukho ukushukuma ngamandla; ivelufa inokuzivalela ngokuzenzekelayo xa kukho ubundlobongela obunobundlobongela;
Ukukhutshwa koxinzelelo oluzimeleyo: kwimeko yomehluko omkhulu woxinzelelo phambi nangemva kwevalve, ivalve inokuvulwa emva kokuba ivalve yokukhupha uxinzelelo ivuliwe. Ngaloo ndlela, i-fuel gas ayiyi kukhutshwa emoyeni, isusa iingxaki ezifihlakeleyo zokhuseleko;
