Type 10
Pressure Regulator Series
Features
Highly Accurate
Pressure Regulation
The Bellofram Type 10 Regulator controls
output pressure with an accuracy of 0.1%,
and has very low sensitivity to changes in
supply pressure and flow.
Start-Up Stability
The Type 10 Regulator has been designed to
eliminate the need for any readjustment of the
regulated pressure after long “down time.”
At start-up, the regulated pressure will return
to its output setting.
Flow Stability
The regulated pressure is held constant over
substantial changes in flow due to the high-gain
pneumatic servo amplifier. Particularly good
from dead end to 20 cubic meters per hour
(12 SCFM).
Automatic High
Downstream Relief Capacity
An integral relief valve provides for exhaust
flow whenever the regulated pressure is reset
to a lower value. The exceptionally large
capacity of this relief valve assures immediate response when the downstream regulated
pressure must be reduced under dead-end
conditions.
Pressure Stability
A high performance servo-operated control
mechanism is utilized in the regulator. The
pressure supplied to the pneumatic servo
amplifier is reduced and held constant.
Locking Capability
The standard Type 10 regulator has a locking
nut which, when tightened, prevents inadvertent adjustment of pressure.
Temperature Stability
Shifts in the regulated pressure over wide
ambient temperature variations are minimized
by the use of a measuring capsule made of
specially selected stainless steel alloys.
Proven Reliability
Thousands of Type 10 Regulators are in the field.
Proof of the accuracy of the regulator is reflected
by its use in most air gauging systems and other
precision pressure control applications.
Mounting
The unit may be installed in any position.
It can be panel mounted or supported by in-line
plumbing.
Applications
Industrial processes, inspection procedures,
control and analytical instrumentation require
precise regulation of air pressure in pipes and
vessels. Maintaining constant pressures in
these applications is usually complicated by
the presence of numerous disturbances, such
as changes in supply pressure, flow, and ambient temperature, that tend to upset prevailing
conditions.
Bellofram Pressure Regulators provide accuracy,
precision control, and maximum stability under
the most adverse operating conditions.

High Relief Regulators
Similar in proven accuracy and rugged construction to other Type 10
Regulators, these units provide extra fast “blowdown” for very rapid
release of down stream pressure. The extra relief feature makes these
regulators suitable for cylinder return stroke actuation, air hoists, and
similar applications requiring fast exhaust.

Tamper Resistant
The Type 10 Regulator is available with
a tamper resistant cover, as illustrated.
The cover is threaded over the adjusting
screw to prevent inadvertent or unwarranted adjustment of output pressure.
Type 10LR
Low Range Regulator
The main feature of the Type 10LR is its low-range pressure characteristic. It operates on a maximum of 50 psig / 3.4 BAR supply pressure and offers an output pressure range of 0.5 psig / 0.03 BAR to 25 psig / 1.7 BAR

Type 10 Motorized
Pressure Regulators
Bellofram’s high precision Type 10 pressure regulator – a servo
balanced system in which the main valve is operated by a pilot
valve – is also available in a motorized configuration. This combination is particularly attractive because it offers low power requirements (2 rpm/4 watts; 6 rpm/6 watts) with extremely high accuracy.
Applications
The motorized Type 10 pressure regulator can be used for any
application where electric control of a pneumatic system is desired.
It is often used for remote pressure control and for ventilation systems. It can also be easily integrated into open or closed loop process
control systems and may be used with programmable controllers.
Features
•Mountable at any angle
•In the event of power failure, the pneumatic output remains
constant at last setting
•Low electrical power requirements
•Adjustable mechanical stop limits maximum output pressure
•No electrical power is required when operating at constant output pressure
•No pre-regulation of supply pressure required
•Built-in overload slip clutch prevents damage to gear train at end of travel,
eliminating the need for limit switches in most applications.
Construction
The regulator and motor are mounted to a bracket and
connected to each other through a flexible coupling. The
assembly can be mounted through holes in the bracket.
Motor Specifications
Reversible, synchronous motor with gear drive
and slip clutch.
Operating Voltage 110VAC, 24VAC, 24VDC or 220VAC.
Frequency
60 Hz, Except 220 VAC model is 50 Hz.
Power Consumption (maximum)
2 rpm/4 watts, 6 rpm/6 watts.
Speeds Available 2 and 6 rpm.
Torque Approx. 8 in. oz.

Air Regulators
Type 110
Pressure Regulator Series
Features
•Highly Accurate Pressure Regulation
•Large Port Sizes Available:
3/8, 1/2, 3/4 and 1 NPT
(BSPP and BSPT also Available)
•Adjustment Stem Locking Capability
•High Forward Flow Capacity – 150+ SCFM
•High Exhaust Capacity
•Balanced Supply Valve
•Low Sensitivity to Supply Pressure Variations
•Low Sensitivity to Flow Variations
Applications
The Type 110 was developed specifically for
use with Air Balancing Systems or Zero-Gravity
Arms. Such systems require very small forward
to reverse flow offsets for smooth operation.
The precision regulators that can achieve the
sensitivity requirements do not typically possess the forward or exhaust capacity to handle
large balancing arms or cylinders. The Type
110 does not have this limitation. It is ideal for
use in any application where precise regulation
of pressure is required along with high flow or
high exhaust capacity.
Other typical applications
•Valve Operators
•Air Hoists
•Web Tensioning
•Roll Loading
•Large Cylinder Loading
•Air Brakes
•Force Balance Hoists
•Gate Actuators
Description
The Type 110 combines the proven technology
of the Marsh Bellofram Type 10 regulator with
the large pneumatic booster of the Type 79
Relay. The result is a precise, crisply responding
regulator that can achieve very large forward
and exhaust flows. Forward to reverse flow
offset is minimized by the capsule operated,
servo-control system located in the upper
portion of the regulator. This servo-control
system supplies a pilot pressure to the large
integral pneumatic booster. The large supply
and exhaust orifices of the integral booster
enable this regulator to produce very high
forward and exhaust flow rates. Few regulators
can offer this combination of sensitivity and
large flow capacity.
As with all of the Type 10 regulators, the
stainless steel measuring capsule is the “heart”
of the Type 110 Pressure Regulator. Originally
developed for sensitive aircraft altimeters, this
precision-sensing element provides the energy
to activate the servo-control mechanism.
It provides greater regulation and accuracy
while eliminating the problems usually
encountered with range springs and conventional diaphragms. Because of the balanced supply
valve in the integral pneumatic booster, the
Type 110 can work with higher supply pressures
(250 PSIG) than many other regulators.

Type 40
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.

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.

Air Regulators
Type 41-1 & Type 41-2
Pressure Regulator Series
Features
•Superior regulation characteristics
•Rugged, corrosion-resistant construction
•Excellent stability and repeatability
•Self-relieving of excess down stream pressure
•Low droop at high flow
•Mounting options available
Description
The Type 41 regulators are designed for applications requiring high flow capacity, low droop,
high accuracy, and fine adjustment sensitivity.
The use of Bellofram’s rolling diaphragm provides greater sensitivity and improved accuracy.
In addition, Type 41 regulators offer reduced
over-all size and several mounting options,
providing direct interchangeability with more
expensive competitors’ units.
Ruggedly designed and constructed, the Type
41 regulators have housings of precision-cast
aluminum. They are pressure tested, and
are chromate treated for internal corrosion
resistance. Every regulator is finished with vinyl
paint which resists scratching, weathering and
other physical abuse.
Careful design and quality materials throughout
assure long, trouble-free operation in the most
difficult industrial environments. A rubberized,
soft-seat valve stem provides stability and
“forgives” dirt and 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 design of these regulators is especially
well suited for panel applications due to ease of
mounting (only one panel hole required), small
size, adjustment sensitivity (32 threads per inch
on the adjusting screw), and knob.
Models
The Type 41 comes in two versions, Type 41-1
and Type 41-2. These two regulators offer the
same performance in two slightly different
packages.
Type 41-1
This unit comes standard with 1⁄4 NPT ports
and a knob, and can be panel mounted using
either the center nut or the threaded shoulder
holes, spaced 1.5 in. (38.1 mm) center-to-center.
Type 41-2
This unit comes standard with 1⁄4 NPT ports,
a knob and a bonnet vent port which can be
tapped for a 1⁄4 NPT fitting if desired. It can
be panel mounted using either the center nut
or the threaded shoulder holes, spaced 1.25 in.
(32.7 mm) center-to-center.
