1. The recommended ranges for use with a V-9502 Positioner are: 3 to 6 psig (21 to 41 kPa) and 3 to 7 psig (21 to 48 kPa) for
N.O. valves, 9 to 13 psig (62 to 90 kPa) for N.C. valves, and 4 to 8 psig (28 to 55 kPa) for three-way valves.
2. 3 to 7 psig (21 to 48 kPa) for MP82 and MP84 Actuators.
3. The maximum closeoff pressure listed is limited to the maximum allowable American National Standards Institute (ANSI)
valve body rating corresponding to the maximum temperature rating (308 psig [2,122 kPa] at 338°F [170°C]) of the valve.
