Test data for the Type 40 regulator shows excellent performance characteristics compared with those of similar units presently on the market. The Type 40 regulator is generally superior in regulated pressure vs. flow, forward-to-reverse flow offset, supply pressure sensitivity, repeatability and stability. Ruggedly designed and constructed, the Type 40 has housings of diecast aluminum. Every regulator is finished with vinyl paint (which resists scratching, weathering and other physical abuse) and is pressure and leak tested prior to shipment from the factory. Careful design and quality materials throughout assure long, trouble-free operation in the most difficult industrial environments. A rubberized, soft-seat valve stem provides positive shut-off and “forgives” dirt or other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs. The gauge port is convenient for gauge installation and can also be used as an additional full flow outlet. The Type 40 regulator has a 60-mesh 304 stainless steel screen to block foreign particles from entering the output stream. The design of these regulators is especially well suited to pilot-operated controllers and instruments, as well as applications such as air chucks, air spray guns, air cylinders and actuators, and a wide range of industrial pneumatic systems and equipment. 90 6.2 80 5.5 70 4.8 60 4.1 50 3.4 40 2.8 30 2.1 20 1.4 10 0.7 0 0 Type 40: Regulated Pressure VS.
