Quick Opening Valve Characteristic
Table 12 contains values that approximate the characteristic of a quick opening control valve. When the
QUIK custom characterization type is selected, the values in Table 12 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.
