Ka la 28, e le moetsi ea ka sehloohong oali-valve tsa pneumatic air damper, re motlotlo ho tlaleha thomello ea lihlahisoa tsa rona tsa boleng bo holimo ho bareki ba rona ba bohlokoa Mongolia.

Ea ronali-valve tsa moeali etselitsoe ho fihlela litlhoko tse khethehileng tsa liindasteri tse hlokang taolo e tšepahalang le e sebetsang ea phallo ea moea le khase. Boholo ba lebitso la sehlopha sena sa li-valve tsa moea ke DN500, 'mele oa valve o entsoe ka thepa ea tšepe ea Q235B, mocheso o loketseng o ka har'a likhato tse 250, khatello ea ho sebetsa ke PN2.5, e tla sebelisoa pompong e lahliloeng.

Pneumatic ea ronasetsiba sa moeali-valve li tsejoa ka litekanyetso tsa tsona tse phahameng tsa moralo le tlhahiso, ho netefatsa hore li tšoarella le ho tšepahala libakeng tse hlokang. Re tsepamisitse maikutlo ho boenjiniere bo nepahetseng le lisebelisoa tsa boleng, li-valve tsa rona li fana ka ts'ebetso e tsitsitseng, e nolofalletsang taolo e nepahetseng ea phallo ea moea le phallo ea khase.
