1.The numbers in the dark boxes indicate the standard specification actuators matched with the valve. 2.The maximum allowable pressure difference shall not exceed the maximum value specified in the ANSI B16.34 standard. 3.The inlet pressure P₁ shall not exceed the maximum allowable pressure difference when the valve is closed. 4.The maximum allowable pressure difference varies with the valve seat leakage. In the same cell, the pressure difference above indicates the condition when the valve seat leakage is ≤ 0.01%, and the pressure difference below indicates the condition when the valve seat leakage is ≤ 0.001%. |
