Li-valve tse sebetsang moo ho batang haholo kapa mochesong o feteletseng li tlameha ho lokisoa hore li sebetsane le liphetoho tse itseng tsa 'mele tse etsahalang libakeng tseo li sebetsang ho tsona.
Li-valve tsa cryogenic, tse sebelisoang lits'ebetsong tse kenyelletsang likhase tse nang le mokelikeli joalo ka LNG kapa oksijene ea metsi, li sebetsa ka mocheso o tlase ho -196 ° C. Lithempereicharang tse tlase joalo, lisebelisoa li fetoha brittle, esita le ho lutla ho honyenyane ho ka baka likotsi tsa ts'ebetso. Li-valve tsena li tlameha ho etsoa ka libonete tse atolositsoeng ho sireletsa kutu ho tsoa mecheng e batang le ho thibela serame kapa sets'oants'o.
Ka lehlakoreng le leng, li-valve tsa mocheso o phahameng li entsoe hore li sebetse tlas'a mocheso o sa khaotseng—hangata o feta 400°C. Tsena li sebelisoa hangata lifemeng tsa motlakase, moo ho hloekisoang teng, le litsing tsa mouoane tse nang le khatello e matla.
