Pressure Regulator Series
Description
Marsh Bellofram’s General Purpose Type 40
Pressure Regulator is a reliable precision unit
designed for instrumentation and general
purpose use.
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.

Air Regulators
Fluorocarbon Pintle
A special elastomeric pintle used where elements in the supply air, such
as flame retardant synthetic lubricants, are particularly destructive to
ordinary pintle material.
Non Relieving
Used in applications where it is desirable to relieve pressure downstream
of the regulator, for some constant flow applications, and where the gas
flowing through the regulator must not escape at the regulator. Non-relieving regulators should not be used for low or no flow applications.
Corrosive Resistant Epoxy Finish
An epoxy paint applied to the body and bonnet of the regulator exterior
surfaces to provide increased corrosion resistance.
Mounting Bracket
Steel (dichromate finish) bracket for side mounting. P/N: 607-000-057
Knob
Option to replace the square head pressure adjusting screw.
Tapped Vent
Allows installation of plumbing to capture exhaust air.
Pressure Gauge
Dual scale 2 in. (50.8 mm) gauges. Ranges include 0-30 psig (0-200
kPa), 0-60 psig (0-400 kPa), 0-100 psig (0-700 kPa) and 0-160 psig
(0-1100 kPa). When specified with regulator, the correct range will be
supplied. For NPT versions only.
Tamper Resistant Cover
An aluminum tubular cover placed over a slotted head adjusting screw and
screwed onto the bonnet of the regulator with a wrench. Prevents ordinary
hand adjustments.
Drawings and
dimensions are
for reference only.
Soft Relief Seat
Used in applications where it is desirable to reduce the standard bleed
rate from 6 SCFH [0.17 m3hr] to less than 0.1 SCFH [0.003 m3hr].
Fluorocarbon Diaphragm
Diaphragm as well as all seals are made of fluorocarbon elastomer to prevent deterioration from elements in the air supply, such as flame retardant
synthetic lubricants normally destructive to standard Nitrile material.
