Type EZR
Pilot
Type PRX/120:
Outlet pressure range of 1 to 40 bar. The Type PRX/120
can be used as the pilot on single stage pressure reducing
regulators or as the monitor pilot or as the working pilot in
wide-open monitor systems.
Type PRX/120-AP:
Outlet pressure range of 30 to 80 bar. The Type PRX/120-
AP can be used as the pilot on single stage pressure
reducing regulators or as the monitor pilot or as the working
pilot in wide-open monitor 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.

• Type 161EB
High accuracy pilot with an outlet pressure range of 0.34 to
24.1 bar. Pilot bleeds (exhausts) downstream through the
sense (control) line.
• Type 161EBM
The monitor version of the Type 161EB pilot. The pilot
bleed (exhaust) is isolated from the sense (control) line.
This pilot is used in monitoring systems requiring an
isolated pilot bleed (exhaust).
• Type 161EBH
The high pressure version of the Type 161EB pilot with an
outlet pressure range from 17.2 to 48.3 bar.
• Type 161EBHM
The high pressure version of the Type 161EBM pilot with
an outlet pressure range from 17.2 to 48.3 bar.
