Type 65 - T65 Regulator Factory Preset
Marsh Bellofram’s General Purpose Type 60 and Type 65 Precision Air Regulators are reliable precision units designed for instrumentation and general purpose use. The Type 60 is a pre-set, fixed-pressure unit with a dripwell. The Type 65 is similar to the Type 60, but without a dripwell. Test data for these regulators show excellent performance characteristics compared with those of similar units presently on the market. These Marsh Bellofram regulators are generally superior in regulated pressure vs. flow, forward-to-reverse flow offset, supply pressure sensitivity, repeatability and stability. Ruggedly designed and constructed, the regulators have housings of diecast aluminum. Both models are finished with vinyl paint (which resist scratching, weathering and other physical abuse), and are pressure and leak tested prior to shipment from the factory.
