The FRI/6 balancing type pressure regulator combines a pressure regulator and a 50 micron gas filter in one housing. Various combinations are possible using the FRI/6 with the most of the DMV shutoff valves for a compact, modular system:

• Stand-alone pressure regulator and gas filter with threaded flanges, or direct mount to DMV sizes 701, 702 and 703 series safety shutoff valves.
• Regulator output pressure monitored by direct mounting an A2 type pressure switch. Additional ports to sense inlet and outlet pressure are also located on the threaded flanges.
• Heavy duty diaphragm construction for durability and strength.
• Steady, precise and instantaneous regulation of the outlet pressure.

Specifications:

• Max. operating pressure: 7 PSI (500 mbar) CE; 5 PSI (360 mbar) CSA
• Input pressure range: 2 to 200 in. W.C. (5 mbar to 500 mbar)
• Output pressure range:
• 4-12″ W.C.(10 to 30 mbar) (Standard Blue Spring)
• Other adjustable Spring Ranges from 1 to 80 in. W.C. (2.5 mbar to 200 mbar); (see accessories below)
• Gas Filter:50 micron; replaceable
• Ambient temperature rating:
• +5F to +150 F for up to 7 PSI for regulating behavior (+/- 10% of setpoint).
• -40F 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.
