11-008
● Designed for systems that require pressure
regulation at an inaccessible location.
● A pilot regulator (ordered separately) controls the
outlet pressure of the pilot operated regulator.
● For general purpose applications, order an R72 or
R07 pilot regulator.
● For precision applications, order an R40, R41, or 11-
104 pilot regulator.
● Constant bleed feature provides quick maximum
sensitivity to system changes

Feedback Pilot Regulator Warning
The feedback line must sense the pilot operated regulator outlet pressure
and must be connected before turning on the air supply. If the feedback line
is not connected, the pilot operated regulator outlet pressure will rapidly
increase to the inlet pressure when the adjusting knob on the pilot
regulator is turned clockwise.

Technical Data
Fluid: Compressed air
Inlet pressure range: 10 psig (0.7 bar) to 400 psig (27.6 bar)*
* For best performance, inlet pressure should be at least 10 psig (0.7 bar) greater than the desired
regulated pressure, but must not exceed the specified maximum.
Operating temperature: 0° to 175°F (-20° to 80°C)**
** Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Typical flow with a conventional pilot regulator at 150 psig (10.3 bar) inlet pressure,
100 psig (6.9 bar) set pressure, and a droop of less than 5 psig (0.35 bar) from
set:
1/2" ports: 70 scfm (33 dm

/s)
3/4" ports: 110 scfm (52 dm3/s)
1" ports: 180 scfm (85 dm

/s)
Maximum bleed rate at 50 psig (3.5 bar) outlet pressure: 0.34 scfm (0.16 dm3/s)†
†Maximum bleed rate occurs under dead-end (no flow) conditions.
