The Posi-flate Series 473 Regulator is designed for exceptionally long life as a remote pilot operated air pressure regulator.
Fluid: Compressed air
Output Pressure Range:
3 psig (0.2 bar) minimum to 175 psig (12.1 bar) maximum, depending upon configuration
| Size | Operating Pressure | Maximum Inlet Pressure |
|---|---|---|
| 1-1/4" | 10-170 psig | 170 psig |
| 2" | 3-80 psig | 80 psig |
| 2" | 5-110 psig | 110 psig |
| 2" | 20-175 psig | 175 psig |
| Normal: | -40° F to 175° F (-40° C to 80° C)* |
| Optimal: | -40° F to 250° F (-40° C to 121° C)* |
* Air supply must be dry enough to avoid ice formation at temperatures below 355° F (22° C).
| 1-1/4" Regulator: | 1100 SCFM (520 dm3/s)** |
| 2" Regulator: | 3000 SCFM (1416 dm3/s)** |
** Typical flow with 100 psig (6.9 bar) inlet pressure, 90 psig (6.3 bar) set pressure, and a drop of 15 psig (1 bar).
