Norgren R24 User Manual
Air line equipment
R24 Micro-Trol Pressure
Regulator
1/4" to 1-1/4" ports
ISO Symbol
Relieving
High flow regulator with exceptional
high relief flow
Adjusting knob can be set in the field
to stop at some maximum pressure
setting or some minimum pressure
setting
Easy to adjust even at high output
pressures
Balanced valve minimizes effect of
variations in inlet pressure on outlet
pressure
Constant bleed feature provides
maximum sensitivity to system
changes
Relieving feature allows reduction of
downstream pressure when the
system is dead-ended

Technical data
Fluid:
Compressed air
Maximum inlet pressure:
300 psig (20 bar)
Operating temperature:
0° to 150°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:
0.031 scfm (0.016 dm3/s) †
† Maximum bleed rate occurs under dead-end (no flow)
conditions.

* Outlet pressure can be adjusted to pressures in excess of, and less than, those specified. Do not use these units to control
pressures outside of the specified ranges.
** A factory installed gauge is only available with PTF threads (A in last position of model number). If a gauge is desired with ISO
threads (B or G in last position), order the desired gauge and appropriate reducing bushing from Accessories.
