BRR - Balanced Ratio Regulators are designed to provide accurate air/fuel ratio control of cross-connected combustion systems. The delivery pressure of the BRR will match that of the cross-connected signal being applied to the upper diaphragm chamber, as long as the minimum differential is maintained. A turndown ratio of 20 to 1 is possible with the BRR. The Balanced Ratio Series features large main diaphragms, a balancing diaphragm and soft rubber seat to insure good control at low turndown ratios.
