Leve valv chèk refere a valv la ki otomatikman louvri epi fèmen disk la depann sou koule nan medyòm nan tèt li pou anpeche mwayen backflow, konnen tou kòm valv chèk, valv yon sèl-fason, valv counterflow, ak valv presyon tounen. Valv chèk se yon valv otomatik. Fonksyon prensipal li se anpeche rflu mwayen, ponp ranvèse ak motè kondwi, ak lage mwayen veso. Tiyo chèk yo ka itilize tou nan tiyo pou bay sistèm oksilyè kote presyon ka monte pi wo pase presyon sistèm lan. Tiyo chèk yo ka divize an valv chèk balanse (wotasyon dapre sant gravite a) ak valv chèk leve (k ap deplase sou aks la).
