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 dm

3

/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 dm

3

/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).

1/4" PTF with PTF main ports
Rc1/4 with ISO G and ISO Rc main ports
