Valve ea boleng bo holimo e ka sebetsa ka letsoho kapa ka boeona. Li-valse tsa methapo li sebelitse ka letsoho ho laola sebaka se pakeng tsa plunger le setulo sa valve. Ha molumo a kena ka tsela e le 'ngoe, plung ea letsoho e phahamisoa hore e bule valve le ho lumella mokelikeli ho feta. Ha molumo oa matsoho o ile oa fetoha ka tsela e 'ngoe, plunger e ea haufi le setulo ho fokotsa sekhahla sa ho phalla kapa ho koala valve.
Li-valse tse ikemetseng li hokahane le koloi ea hydraulic kapa sehlopha sa moea se bulang ebe se koala valve. Motor kapa sehlopha sa letsoho se tla fetola boemo ba plungo ho ea ka nako ea li-time kapa data ea ts'ebetso ea kantle e bokelletsoeng ha ho lekola mochine.
Li-valse tse sebetsang ka letsoho le tse ikemetseng li fana ka taolo e nepahetseng ea sekhahla sa phallo. Kamore ea letsoho e se e khaphatsehile, e bolelang ho nka liphetoho tse ngata ho fetola boemo ba plunger. Ka lebaka leo, valve ea nale e ka u thusa ho tsamaisa sekhahla sa ho phalla ha metsi tsamaisong.
