used as the pilot on single-stage pressure reducing
regulators or as the monitor pilot or working pilot in
wide-open monitor systems. The Type PRX has a
double diaphragm which provides increased accuracy
and sensitivity, an integral restrictor adjustment which
allows adjustable opening and closing speeds, and
a damper adjustment which adjusts inlet pressure
variability and loading pressure oscillations.
Type PRX/120-AP
—Outlet pressure range of 435 to
1000 psig (30,0 to 69,0 bar). The Type PRX/120-AP
can be used as the pilot on single-stage pressure
reducing regulators, as the monitor pilot or working
pilot in wide-open monitor systems, or as the working
pilot for monitoring and working regulators in the
working monitoring systems.
Type PRX/125
—Identical to the Type PRX/120 except
the restriction screw is removed. The Type PRX/125
can only be used as the monitor override pilot on
working monitor applications.
Type PRX/125-AP
—Identical to the Type PRX/120-AP
except the restriction screw is removed. The
Type PRX/125-AP can only be used as the monitor
override pilot on working monitor applications.
Note
For applications requiring extremely
tight control, using a Type 161AYM or
161EBM monitor pilot will increase the
accuracy of the regulator.

1. See Table 1 for structural design ratings, Table 3 for pilot ratings, and Table 10 for maximum pressure ratings.
2. The white and yellow springs are only recommended for inlet pressures under 100 psig (6,9 bar).
3. The red, black, purple, red stripe, and black with white stripe springs are only recommended for applications where the maximum inlet pressure can exceed 500 psig (34,5 bar).
