1. Li-valve tse khaotsoeng li loketse liphaephe kapa lisebelisoa tse nang le mocheso o phahameng le khatello e phahameng ea litaba. Joalo ka lifeme tsa matla a futhumatsang mocheso, litsi tsa motlakase oa nyutlelie, mocheso o phahameng le liphaephe tse nang le khatello e phahameng ea litsamaiso tsa petrochemical.
2. Li-valve tsa globe li sebelisoa liphaepheng moo ho hanyetsanang le convection ho sa hlokahaleng ka thata. Ke hore, tahlehelo ea khatello ha e eloe hloko.
3. Li-valve tsa nale, li-valve tsa lisebelisoa, li-valve tsa sampling le li-valve tsa nale ea khatello ke khetho bakeng sa li-valve tse nyenyane.
4. Ho na le taolo ea phallo kapa taolo ea khatello, empa ho nepahala ha taolo ha ho phahame, 'me bophara ba pipeline bo batla bo le nyane. Bakeng sa phaephe e nang le tsela e sa feteng 50 mm, valve e khaotsoeng e lokela ho khethoa.
5. Khatello e phahameng ea angular globe valve kapa khatello e phahameng ea angular throttle valve e nang le khatello ea lebitso PN160 16 MPa kapa PN320 32 MPa e lokela ho khethoa bakeng sa menontsha ea lik'hemik'hale tse nyenyane le tse kholo tlhahisong ea maiketsetso ea indasteri.
6. Sebakeng sa desiliconization workshop le coke-prone pipeline ea alumina Bayer process, ho bonolo ho khetha valve ea globe e tobileng-hona joale kapa valve ea throttle e tobileng e nang le 'mele o arohaneng oa li-valve, setulo se fumanehang le para ea ho tiisa carbide.
7. Mererong ea phepelo ea metsi le ea mocheso mohahong oa litoropo, liphaephe tsa mabitso li feta ho tse nyane, 'me li-valve tsa globe, li-balance valve kapa li-plunger valve li ka khethoa, joalo ka liphaephe tseo liphaephe tsa mabitso li fetang ka tlase ho 150 mm.
