Basebetsi ba ka hare ho li-valve ba sebetsa libakeng tse boima haholo, ba tobaneng le:
Khoholeho ea mobu: E bakoang ke metsi a lebelo le phahameng kapa a tletseng likaroloana.
Corrosion: Ho tsoa mecheng ea litaba e mabifi ka lik'hemik'hale.
Cavitation: Ho thehwa le ho putlama ha dipudula tsa mouoane, ho baka ho putlama ha bokahodimo.
Khatello e Phahameng/Mocheso: E lebisang ho qhekella (ho roala sekhomaretsi) le ho senyeha.
Ho loantša litaba tsena, li-valve tsa ka hare li atisa ho etsoa kapa ho sireletsoa ka thepa e tsoetseng pele, 'me tungsten carbide e le khetho e phahameng bakeng sa litšebeletso tse matla ka ho fetisisa.
Tafole e latelang e akaretsa li-valve tse tloaelehileng, liphephetso tsa bona, le litharollo tse tloaelehileng tsa thepa:
| Karolo | Mosebetsi | Mekhoa e Tloaelehileng ea ho Wear | Litharollo Tse Tloaelehileng tsa Lintho |
| Setulo | E fana ka sebaka sa tiiso bakeng sa ho koala. | Khoholeho ea mobu, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite (Cobalt-Chrome), 316SS, Alloy 6, Ceramics. |
| Setho sa ho Koala (Plug/Disc) | E tsamaela ho bula/ho koala tsela ea phallo. | Khoholeho ea mobu, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite, 316SS, Litšepe tse thata. |
| Motsoako | E fetisetsa motsamao ho tloha ho actuator ho ea ho setho se koalang. | Abrasion, Mokhathala, Corrosion. | 17-4PH Stainless Steel, Nitrided Steels, Corrosion-Resistant Alloys. |
| Lesaka | E tataisa plug le ho laola litšobotsi tsa phallo. | Khoholeho e Matla, Cavitation, Lerata / Vibration. | Tungsten Carbide, Stellite, 316SS, Duplex Stainless Steels. |
| Litiiso & Gaskets | E thibela ho lutla ka ntle le ka hare. | Extrusion, Ho senyeha ha Lik'hemik'hale, Botsofali ba Mocheso. | PTFE (Teflon), Grafoil, Elastomers (Viton, EPDM). |
Hobaneng Tungsten Carbide bakeng sa Balve Internals?
Lits'ebetsong tse mahlonoko tse fumanoang indastering ea oli le khase, tlhahiso ea matla le lik'hemik'hale, tungsten carbide e hlalositsoe bakeng sa likarolo tsa trim ka lebaka la eona:
Khanyetso e Ikemetseng ea Khoholeho: Ho mamella lehlabathe le makumane a mang a thata a molapo.
Hantle-ntle Cavitation Resistance: Ho thatafala ha eona ho thibela tahlehelo ea thepa hore e se ke ea kenya lipompong tsa mouoane.
Matla a Matla a Phahameng: Ho hanela deformation tlas'a khatello e phahameng.
Khahlano e Ntle ea Galling: Ha e kopantsoe le thepa e lumellanang, e fokotsa kotsi ea ho hapa.
Ka kakaretso, Li-valve tsa ka hare ke pelo ea valve. Khetho ea bona, haholo-holo khetho ea lisebelisoa tse manganga joaloka tungsten carbide bakeng sa likarolo tsa trim, ke qeto ea bohlokoa ea boenjiniere e khethollang ka ho toba tshebetso ea valve, bophelo ba tšebeletso, le polokeho ea tsamaiso ka kakaretso maemong a thata a ts'ebetso.
