The 5101-20-BZR is a balanced zero regulator that has a 2-1/2" inlet and outlet connections with 0.1 W.C. accuracy for low flow & 0.3 W.C. for full flow. It has a 14" W.C. maximum pressure differential, 2 psi maximum inlet pressure, and up to 150°F operating temperature.
The balanced zero regulator is suitable for combustion systems such as proportioning pre-mixers, nozzle mixers, and mixing tees for positive or negative combustion chamber pressures. The unit provides accurate heated gas pressure delivery over the full flow range.
The 5101-20-BZR replaces part number 20-BZR-20.
Easy to install and mounted in a stem-up position within a horizontal line. It also features a large diaphragm-actuated valve assembly that is balanced at almost zero pressure.
