Ho utloisisa li-valve tsa taolo ea Steam

Ho theola ka nako e tšoanang khatello ea mouoane le mocheso ho isa boemong bo hlokoang ke boemo bo itseng ba ho sebetsa, mouoaneli-valve tse laolangli sebelisoa. Lisebelisoa tsena hangata li na le likhatello tse phahameng haholo tsa ho kena le mocheso, tseo ka bobeli li tlamehang ho fokotseha haholo.
