PYRONICS BZR AIR/GAS RATIO REGULATOR

Features & Benefits : Balanced Zero Regulators feature a rugged, large diaphragm actuated valve assembly sensitively balanced at near zero pressure. Gas flow is initiated by a very small pressure differential across the main diaphragm. Gas supply is precisely modulated on system demand by negative or positive signals from suction mixers or controlled pressure from an external source. The BZR regulator assures dependable, precise gas flow control on all types of combustion systems. Now available in a smaller 1/2" pipe size.
