Lisebelisoa tsa li-valve li kenyelletsa li-positioner, li-transducers, li laola khatello ea thepa, li-valve tsa solenoid, li-dampers le li-switch switches.

1. Khetho le tšebeliso ea li-valve tsa taolo
Khetho e nepahetseng ea li-valve tsa ho laola le hore na ho finyella litlhoko tse boletsoeng tsa taolo ea maemo a ho sebetsa ea senotlolo, empa hape le ho netefatsa ts'ireletso ea ts'ebetso. E le ho finyella litlhoko tsa maemo a boletsoeng, khetho ea li-valve tsa taolo e lokela ho ela hloko mofuta oa 'mele oa valve, sebopeho le thepa ea likarolo tsa valve, mofuta oa actuator le ntlha ea tšireletso le lintho tse ling, mofuta o khethiloeng oa li-valve tsa taolo ke motsoako o nepahetseng.

2. Lintlha tsa khetho ea li-valve tsa taolo tse lokelang ho nahanoa
Ho khetha valve ea taolo e loketseng maemo, ho hlokahala hore u nahane ka botlalo ka phello ea khetho ea valve ea taolo ea maemo a fapaneng a ts'ebetso. Tlhahisoleseding ea bohlokoa ka ho fetisisa e kenyelletsang taolo ea mofuta oa mokelikeli, mocheso oa mokelikeli, viscosity ea mokelikeli, matla a khoheli a itseng a metsi, matla a mangata le a fokolang a phallo, khatello e phahameng le e fokolang ea ho kena ha valve, khatello e phahameng le e fokolang ea phallo ea valve, khatello theoha tlas'a maemo a tloaelehileng a phallo, palo ea baahi le phaephe ea ho tsoa le botenya ba lebota.

3. Mokhoa oa ho khetha li-valve tsa taolo
Mokhoa oa ho khetha valve e nepahetseng ea ho laola ho finyella litlhoko tsa kopo ea maemo, mokhoa oa ho khetha mokhoa oa ho laola bonyane o hloka ho nahana ka mokhoa o latelang. Etsa qeto ea maemo a mosebetsi: ho kenyelletsa le palo ea li-valve le ho tsoa ha khatello e phahameng ea phapang, maemo a holimo, a fokolang le a tloaelehileng a ts'ebetso ea lebelo la phallo, mocheso oa mokelikeli le lerata le amohelehang. Bala C-value e hlokahalang, 'me u tsebe boemo ba lerata, cavitation le flashing ka ho bala ℃-value). Khetho ea mofuta oa li-valve tse ka hare: Haeba boleng ba lerata bo lekantsoeng bo feta moeli o lumelloang ke tikoloho ea mosebetsi, joale khetho ea li-valve tsa ho fokotsa lerata e lokela ho nkoa. Haeba cavitation e baloang kapa boleng ba khanya ea valve mosebetsing o boletsoeng tlas'a tšebeliso ea nako e telele ea tšusumetso e kholoanyane, e lokela ho nkoa ka maemo a boletsoeng a anti-cavitation le anti-flash valve components.
