Max. operating pressure

7 PSI (500 mbar) UL and CE

5 PSI (350 mbar) CSA

Max. body pressure

15 PSI (1000 mbar)

Input pressure range

2 in. W.C. to 200 in. W.C. (5 mbar to 500 mbar)

Output pressure range

1 in. W.C. to 60 in. W.C. (2.5 mbar to 150 mbar);

adjustable with different springs

Actual outlet pressure is +/- 15 % of set pressure (15 % hystersis/droop)

Materials in contact with gas

Housing:

Aluminium

Seals and diaphragms:

NBR-based rubber

Ambient temperature rating +5 °F to +150 °F for up to 7 PSI for regulating behavior (+/- 10 % of setpoint).

-40 °F to +150 °F: Diaphragms are suitable for the low temperature, but there

may be out of range regulating behavior.

CSA Certified for -40 °F to +150 °F for up to 5 PSI.

-15 °C to +70 °C applies to the CE Marking.

Installation position

Regulator dome from vertically upright to lying horizontally

Test ports/

Pressure switch mounting ports

One G 1/8 ISO 228 test ports on each side of regulator, sensing downstream

pressure, and one on each inlet and outlet flange (if used as a stand alone regulator).

Gas filter (standard)

50 micron; replaceable

Vent line / Back loading port/

Breathing plug

Vent line connection is G 1/4 ISO 228. The FRI also has a factory installed vent

limiter

, which limits the escape of gas to less than 0.5 CFH @ 5 PSI in case atmospheric diaphragm ruptures. Venting required unless otherwise accepted by the authority having jurisdiction.

Hysteresis/Droop

Hysteresis is less than 10 % for up to 7 PSI inlet.

Average droop at 20:1 turndown is 10 % for up to 7 PSI
