11-104

● Pilot regulators are used to control the outlet

pressure of a pilot operated regulator (ordered
separately)

● The pilot regulator is installed in an accessible

location in the compressed air system; pilot operated
regulator is installed at any point without regard to
accessibility

● Feedback pilot regulator provides superior pressure

regulation under changing flow demands where
changes in flow demand are not sudden or cyclic.

● Constant bleed feature provides maximum sensitivity

to system changes

● Relief feature allows reduction of downstream

pressure when the system is dead-ended

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) maximum*

* 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).

Maximum bleed rate at 50 psig (3.5 bar) outlet pressure:

0.25 scfm (0.12 dm3/s)†

†Maximum bleed rate occurs under dead-end (no flow) conditons.

Pilot ports: 1/4" PTF
Feedback port: 1/8" PTF
