1. The recommended spring 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 Actuators.
3. The maximum valve fluid temperature is as follows:
Actuator Style Water Saturated Steam
V-3801-8001 248°F (120°C) 15 psig (103 kPa)
V-3000-8011 284°F (140°C) 38 psig (262 kPa)
V-3000-8003 248°F (120°C) 15 psig (103 kPa)
MP82 284°F (140°C) 38 psig (262 kPa)
