Pilot Operated Regulator Series 473

The Posi-flate Series 473 Regulator is designed for exceptionally long life as a remote pilot operated air pressure regulator.

High flow
Rapid and accurate response to changes in pilot pressure
Balanced design of internal components keeps constant outlet pressure despite changes to inlet pressure
1/4" NPT inlet and outlet gauge ports
Zero flow shut-off

Fluid: Compressed air

Output Pressure Range:

3 psig (0.2 bar) minimum to 175 psig (12.1 bar) maximum, depending upon configuration

Maximum Inlet Pressure:

Operating Temperature:

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).

Maximum Flow Rate:

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).
