Nerjaveèi asye ba-tanperati fèmen valv pòtay, sifas la sele ka sèlman konte sou presyon medya yo sele, se sa ki, konte sou presyon medya yo pral sifas la sele nan pòtay la nan lòt bò a nan chèz la valv asire ke sifas la poze sele. nan sifas la sele, ki se pwòp tèt ou-sele. Pifò nan valv la pòtay yo itilize fòse sele a, se sa ki, lè valv la fèmen, konte sou fòs ekstèn fòse pòtay la nan chèz la valv asire ke sifas la sele nan sele a.
When the valve is opened, when the gate lifting height is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely open, but in operation, this position can not be monitored. In actual use, it is the apex of the valve stem as a mark, i.e., the position of opening motionless, as its fully open position. In order to take into account the temperature changes in the phenomenon of locking, usually open to the apex of the position, and then back 1/2-1 turn, as the fully open position of the valve. Therefore, the valve's fully open position, according to the position of the gate (i.e., travel>pou detèmine.
