Valve ea Nale ea boleng bo holimo e ka sebetsa ka letsoho kapa ka bo eona. Li-valve 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 fetoleloa ka lehlakoreng le le leng, plunger e phahamisoa ho bula valve le ho lumella mokelikeli ho feta. Ha lebili la letsoho le fetoleloa ka lehlakoreng le leng, plunger e atamela haufi le setulo ho fokotsa sekhahla sa phallo kapa ho koala valve.
Li-valve tsa nale tse ikemetseng li hokahantsoe le enjene ea hydraulic kapa mochini o kenyang moea o bulang le ho koala valve ka bo eona. Enjene kapa actuator e tla fetola boemo ba plunger ho latela nako kapa data ea ts'ebetso ea kantle e bokelletsoeng ha ho lekola mochini.
Li-valve tsa nale tse sebelisoang ka letsoho le tse ikemetseng li fana ka taolo e nepahetseng ea sekhahla sa phallo. Lebili la letsoho le khoele hantle, ho bolelang hore ho nka nako e ngata ho lokisa boemo ba plunger. Ka lebaka leo, valve ea nale e ka u thusa ho laola hantle lebelo la phallo ea mokelikeli tsamaisong.
