7218 REGULATORS accurately maintain a constant air/gas ratio over a wide range of firing rates in both nozzle-mix and premix gas burner systems. Molded diaphragms ensure excellent tracking, repeatability, maximum flows, and superior turndown.
Nozzle-mix Burners
When used with nozzle-mix burners, the vent of a 7218 Regulator is cross-connected to the main air line downstream ...
Hauck RRG regulators are carefully factory balanced to maintain a precise gas-air ratio for nozzle mix burners which use low pressure air and gas. When cross-connected to a control air line (see typical ...
Eclipse Ratio Regulators
The ES-Series ratio regulators are used in applications where gas to air proportional flow is required. The gas flow is controlled as a function of the air pressure through a loading line ...
