Valve ea nale ea boleng bo holimo e ka sebetsa ka letsoho kapa ka bo eona. Livalve tsa nale tse sebelisoang ka letsoho li sebelisa lebili la letsoho ho laola sebaka se pakeng tsa plunger le setulo sa valve. Ha lebili la letsoho le reteleha ka lehlakoreng le leng, plunger e phahamisoa ho bula valve le ho lumella mokelikeli ho feta. Ha lebili la letsoho le reteleha ka lehlakoreng le leng, plunger e atamela setulo ho fokotsa sekhahla sa phallo kapa ho koala valve.
Li-valve tsa nale tse iketsang li hokahantsoe le enjene ea hydraulic kapa actuator ea moea e bulang le ho koala valve ka bo eona. Enjene kapa actuator e tla lokisa boemo ba plunger ho latela li-timers kapa lintlha tsa ts'ebetso ea kantle tse bokelletsoeng ha ho beoa leihlo mochini.
Li-valve tsa nale tse sebelisoang ka letsoho le tse iketsang li fana ka taolo e nepahetseng ea sekhahla sa phallo. Lebili la letsoho le na le khoele e ntle, ho bolelang hore ho nka linako tse ngata ho lokisa boemo ba plunger. Ka lebaka leo, valve ea nale e ka u thusa ho laola sekhahla sa phallo ea mokelikeli tsamaisong hamolemo.
