Equal Percentage Valve Characteristic
Table 9 contains values that approximate an equal percentage valve characteristic in the actuator. When the
EQUL custom characterization type is selected, the values in Table 9 are automatically loaded into the
actuator configuration to produce the characteristic as presented in the graph. The Xn VAL is the input
value as a percentage of range and Yn VAL is the characterized output (actuator shaft position) as a
percentage of range.
