Supply Pressure Ranges
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 MR95H regulator (see figure 3). 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. Constructions are
available in two maximum supply ranges.
When Normally Used With Diaphragm Actuators: Up
to 2.8 bar (40 psig)
When Normally Used With Piston Actuators: Up to
10.3 bar (150 psig)
