11-042
● Designed for systems that require high flow or
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.
● Exceptionally high relief flow.

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