Description
7216 Variable Ratio Regulators are used with nozzle-mix burners to achieve temperature uniformity while using minimum excess air. Molded diaphragms ensure excellent tracking and repeatability, maximum flows, and superior turndown. A high quality stainless steel spring is used to bias the 7216 Regulator air/gas ratio. As air rate is turned down towards low fire, gas rate drops faster, giving increasing percentages of excess air. Reduced total air means greater fuel economy.
The 7216 spring gives the regulator the ability to lock-up for use with a By-Pass Kit. The By-Pass Kit is used to maintain low fire with low or no impulse pressure to the regulator. Make sure to set the by-pass flow rate before adjusting the regulator spring to its desired operating point.
