Lihlopha tsa Li-valve
Li-valve tsa tšepe tse Fepisitsoeng
1. Li-valve tsa Heke ea Tšepe e Fepisitsoeng (Sehlopha sa 800): Moralo o kopanetsoeng bakeng sa ho itšehla thajana ka khatello e phahameng ea oli / khase.
2. Li-valve tsa tšepe tse entsoeng ka tšepe: Taolo e nepahetseng ea phallo litšebeletsong tsa mouoane kapa tsa lik'hemik'hale.
3. Li-valve tsa Tlhahlobo ea Tšepe e Fepisitsoeng: Thibela ho khutlela morao ho li-compressor kapa lipompo (mefuta ea swing / lifti).
4. Li-valve tsa Bolo ea Tšepe e Fepisitsoeng: Ho koaloa ka potlako liphaepheng tsa hydrocarbon tsa Sehlopha sa 800.
Li-valve tsa tšepe tse betliloeng
1. Li-Valves tsa Cast Steel Gate (Sehlopha sa 150–300): Ho itšehla thajana hoa metsi a mangata ho hloekisa metsi.
2. Li-Valves tsa Cast Steel Globe: Taolo e akaretsang ea phallo ho litsamaiso tsa HVAC.
3. Li-valve tsa ho hlahloba tšepe ea Cast: Litharollo tsa theko e tlase bakeng sa lits'ebeletso tse seng tsa bohlokoa.
