Supply Pressure Ranges

(1)

When used in conjunction with a positioner or other
pneumatic accessory, always pipe the positioner and
booster with one common supply through a Fisher
67D, 67DR, or 95H regulator (see figure 4). A
high‐capacity filter, such as the Fisher 262K, should
be installed in the supply line to the regulator. Supply
pressure also must not exceed the maximum
pressure rating of the actuator.
