The Bellofram 961-159-000 Type 79 High Flow Precision Volume Booster/Air Relay uses an air pilot signal to accurately control output pressure over a wide range of flow and supply pressure variations. Superior rolling diaphragm design provides greater sensitivity, lower droop, and improved accuracy when compared to most competitive general purpose flat diaphragm regulators. These regulators are self-relieving and utilize a 1:1 ratio pilot signal vs. output pressure. An electro-pneumatic regulator, transducer or remote pilot regulator typically supplies this pilot signal. Careful design and quality materials throughout assure long, trouble-free operation. Regulators can be pipe mounted or use optional mounting bracket.
