The Dungs 226-460 FRG 710/6 is a spring-loaded ratio regulator and zero governor designed for commercial and industrial gas burner applications. This 1" NPT regulator provides steady outlet pressure control and can help maintain a gas/air ratio during burner turndown or regulate fuel pressure near atmospheric pressure in zero governor applications.
The FRG 710/6 includes an adjustable setpoint spring, defined counterspring, internal outlet pressure sensing, and a standard air impulse line connection. It is suitable for dry natural gas, propane, butane, air, inert gases, and dry H2S up to 0.1% by volume. The unit is CSA certified and intended for installations covered by applicable commercial and industrial fuel gas standards.
The regulator includes 1/4" NPT inlet and outlet test ports on both sides, aluminum housing construction, NBR seals and diaphragms, and a factory-installed vent limiting device. The FRG 710/6 has a 7 PSI factory maximum operating pressure rating and is CSA certified for 5 PSI operation. It supports ratio regulator output from 0 to 60 in. W.C. and zero governor output from -2 to 2 in. W.C.
