Flow Characteristics
All valves have modified linear flow character-
istics. That is, the flow rate is nominally propor-
tional to the valve plug lift, at a constant differen-
tial pressure.
Temperature Pressure Ratings
Consult the appropriate valve linkage general instruction sheet for the
effect of valve body ambient temperatures on specific actuators. Ratings
conform with published values and disclaimer.
