NOTES:
1 These values also apply to the DFC Size 3220-4 actuator.
2 Actuator travel may be less than the value listed after connected to the valve.
3 Maximum actuator travel for the 3220-4 is 4 inches (102 mm).
4 See Specification section for definitions.
5 This Maximum Casing Pressure is not to be used for normal operating pressure. Its purpose is to allow for
typical regulator supply settings and/or relief valve tolerances.
