DUNGS FRI Series

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.
• Lock-up type regulator.
• Factory installed vent limiter. Review applicable codes for vent line requirements.
