The Type 50 pressure regulator is a Filter / Regulator with the
additional feature of a filter and moisture bowl. Manual draining
of the bowl is required. This is an ideal instrument regulator for
actuator control as well as instrument supply. Rugged die cast
aluminum body and bonnet, Nitrile elastomers and an exterior vinyl
paint. The design of these regulators is well suited to
pilot-operated controllers and instrument s, applications such as
air chucks, air spray guns, air cylinders and actuators, plus a
wide range of industrial pneumatic systems and equipment

Dc T 6 (Non-electrical certification) Applications The design of
these regulators is well suited to pilot-operated controllers, and
instruments, applications such as air chucks, air spray guns, air
cylinders and actuators, and a wide range of industrial pneumatic
systems and equipment. Type 50 Pressure Regulator Series
Description Marsh Bellofram’s General Purpose Type 50 and Type 50
NACE Filter Regulators are reliable precision units designed for
instrumentation and general purpose use in both standard
environments (Type 50), and corrosive environments (Type 50 NACE).
The Type 50 NACE complies with NACE material requirement #MR0175
for sulfide stress cracking resistant metallic material for
oilfield equipment. 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. Type 50 NACE Pressure Regulator Series
Ruggedly designed and constructed, the regulators have housings of
die cast aluminum. The Type 50 Regulator is finished with vinyl
paint (which resists scratching, weathering and other physi cal
abuse), while the Type 50 NACE is finished with epoxy paint for
added protection. Both models are 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 50 regulators include a
unique self-cleaning 40 micron nylon mesh filter (316 stainless
steel in the Type 50 NACE) that can be easily removed
