Equal Percentage Valve Characteristic
Table 11 contains values that approximate an equal percentage valve characteristic in the actuator. When
the EQUL custom characterization type is selected, the values in Table 11 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.
