● Fast response
● Minimum overshoot during flow changes
● Precision regulation obtained by pilot valve design -
small change in the pilot valve position results in a
large change in the main valve position
● Constant bleed feature provides maximum sensitivity
to system changes
● Relieving feature allows reduction of downstream
pressure when the system is dead-ended

Ordering Information. Models listed have PTF threads, hand wheel adjustment, and relieving diaphragm. A gauge is not included.
* 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.
† Typical flow with 100 psig (7 bar) inlet pressure, 60 psig (4.1 bar) set pressure and 0.125 psig (0.009 bar) droop from set.
†† Typical flow with 200 psig (14 bar) inlet pressure, 60 psig (4.1 bar) set pressure and 0.250 psig (0.017 bar) droop from set.
Note: 5 micron prefiltration required.

Technical Data
Fluid: Compressed air
Low Pressure Models:
11-018-100 and 11-018-146
High Pressure Models:
11-018-110
Inlet pressure range*
Low Pressure Models: 8 to 150 psig (0.55 to 10.3 bar)
High Pressure Models: 10 to 200 psig (0.7 to 13.8 bar)
* Inlet pressure must be at least 7 psig (0.5 bar) greater than the adjusted outlet pressure for
proper operation.
Operating temperature*: 32° to 160°F (0° to 70°C)
** Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Flow capacity with 100 psig (6.9 bar) inlet pressure
11-018-146: 12 scfm (5.7 dm3/s) with set pressure of 10 psig (0.7 bar)
11-018-100 and 11-018-110: 20 scfm (9.4 dm
3
/s) with set pressure of 20 psig
(1.4 bar). A small pressure droop occurs at flows above 12 scfm (5.7 dm3/s).
Repeatability
Low Pressure Models: 0.02 psig (0.001 bar) for flow change; 0.05 psig
(0.004 bar) when turning supply off and on
High Pressure Models: 0.08 psig (0.006 bar) for flow change;0.16 psig
(0.011 bar) when turning supply off and on
Constant bleed feature:Under dead-end conditions, a small, constant bleed of pilot
air will escape thru the relief passage in the bottom plug.This will be accompanied
by a slight residual outlet pressure of 1 to 4 inches H
2
O (2.5 to 10 millibar).
