Li-valve ke sesebelisoa se sebelisoang haholo se ka fumanoang hoo e batlang e le kae kapa kae, li-valve li sebetsa literateng, matlong, lifemeng tsa motlakase le litsi tsa pampiri, lihloekisi le meaho e fapaneng ea indasteri le ea indasteri.
Ke liindasteri life tse supileng tseo li-valve li sebelisoang hangata le hore na li sebelisa li-valve joang:
1. Indasteri ea matla
Litsi tse ngata tsa motlakase li sebelisa libeso tsa khale le li-turbine tsa lebelo le phahameng ho fehla motlakase.Li-valve tsa hekeli khethoa bakeng sa lisebelisoa tsa ho tima / ho tima tsa motlakase.Ka linako tse ling ho sebelisoa li-valve tse ling, joalo kaLi-valve tsa Y globe.
