The Pyronics BZR zero gas regulator is designed for ambient temperatures up to a continuous operating range of 150° F for precise control of heated gases or higher ambient operating conditions. 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.
BZR regulators deliver gas at a precise pressure, even with slight inlet pressure variations and assures dependable, precise gas flow control on all types of combustion systems including proportioning premixers, nozzle mixers and mixing tees at positive or negative combustion chamber pressures. The patented regulator design assures highest accuracy over full flow range: With no friction between sensitively counterbalanced parts, fast, positive response is assured.
