Gas Appliance Pressure Regulators withintegrated gas filter
FRI/6 Series
DescriptionThe FRI/6 pressure regulator combines a pressure regulator and a 50 micron gas filter in one housing.Various combinations are possible us-ing 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 pres-sure switch. Additional ports to sense inlet and outlet pressure are also located on the threaded flanges.
- Precise and accurate regulation.
- Lock-up type regulator (The outlet pressure shall not rise more than 15% or 3 in. W.C, whichever is greater, above the setpoint).
- Factory installed vent limiter. Review applicable codes for vent line require-ments.
ApplicationThe FRI/6 pressure regulator is recom-mended for industrial and commercial heating applications and is suitable for natural gas, propane, butane, air and inert gases. Suitable for up to 0.1% by volume, dry H2S.
