Sehlahisoa sena ke valve ea bolo ea lebili la ketane, e entsoeng ka thepa e matla haholo, e nang le litšobotsi tse kang ho hanyetsa ho roala, ho hanyetsa kutu, le ho hanyetsa mocheso o phahameng. E sebelisoa haholo liindastering tse kang lik'hemik'hale, peterole le matla, bakeng sa ho laola le ho khaola mecha ea litaba ea mokelikeli liphaepheng.
Valve ena ea bolo e nka moralo o tsamaisoang ke sprocket, o fokotsang torque ea ts'ebetso mme o nolofalletsa ts'ebetso. Ho sa le joalo, sebopeho se kopane, ho bonolo ho se kenya, 'me ho bonolo ho se hlokomela.
Re fana ka mefuta e mengata le litlhaloso tseo u ka khethang ho tsona, 'me tafole e ikhethileng e tjena:
| Mohlala | Nominal Diameter | Khatello ea ho Sebetsa | Mocheso oa ho sebetsa | Mecha ea litaba e loketseng |
|---|---|---|---|---|
| D341X-16 | DN50-DN200 | 1.0-1.6 MPa | -29-425 ℃ | Metsi, Mouoane, Oli, joalo-joalo. |
| D343H-16P | DN50-DN200 | 1.0-1.6 MPa | -29-425 ℃ | Metsi, Mouoane, Oli, joalo-joalo. |
| D941X-16 | DN50-DN200 | 1.0-1.6 MPa | -29-425 ℃ | Likhoerekhoere, Ho etsa lipampiri, Liindasteri tsa Petrochemical, joalo-joalo. |
Lihlahisoa tsa rona li na le boleng bo ka tšeptjoang le ts'ebetso e tsitsitseng, 'me li tšeptjoa haholo ebile li rorisoa ke bareki ba rona. Haeba u na le lipotso kapa u hloka lintlha tse ling mabapi le lihlahisoa tsa rona, ka kopo ikutloe u lokolohile ho ikopanya le rona 'me re tla thabela ho u sebeletsa.
