Notes: If the actuator is equipped with an auxiliary air supply, the smaller one of the two supply pressures shall be selected as the basis for calculating the allowable pressure difference. The maximum allowable pressure difference shall not exceed the maximum value specified in ANSI B16.34 or JIS B2201 standards. In the same cell, the number above represents the allowable pressure difference when the valve is fully open, and the number below represents the allowable pressure difference when the valve is closed.
