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).
