Precision
- Type 10 |
|
| There
is no other self-contained pressure regulator in the
entire world, which can match the regulation accuracy
and the repeatability of the Bellofram Type
10 pressure regulator. It is for use where
the utmost precision is required. The regulator is
actually a pressure controller using a servo-balanced
system in which the main valve is operated by a pilot
valve and is dependant on a stainless steel measuring
capsule for its incredible accuracy. Originally developed
for sensitive aircraft altimeters, this precision
sensing element provides the energy to activate the
servo-control mechanism. It provides greater regulation
accuracy and eliminates the problems usually encountered
with range springs and conventional diaphragms. The
entire measuring element, including the pilot valve,
is fabricated from stainless steel which has been
carefully heat treated to eliminate hysterics or permanent
deformation under all working conditions. |
|
|
|
|
The Bellofram Type 10 regulators
output pressure with an accuracy of 0.1%, and has
very low sensitivity to changes in supply pressure
and flow. 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. The regulated pressure is held
constant over substantial changes in flow due to the
high-gain pneumatic servo amplifier and is particularly
good from dead end to 12 SCFM. 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
is achieved by a high performance servo-operated control
mechanism utilized in the regulator and the pressure
supplied to the pneumatic servo amplifier is reduced
and held constant. |
|
|
|
|
Applications
for the Type 10 Pressure Regulator include;
Gas Mixing, Valve
Operators, Gate Actuators, Positioner Signal, Air
Hoists, Calibration Stands, Disc and Shoe Air Brakes,
Force Balance Hoists, Air Gauging, Clamp Units, Web
Tensioning, Press Units, Roll Loading, and Cylinder
Loading |
|
Motorized
Type 10
The
Bellofram Type 10 is also offered coupled
with a bi-directional motor for electronic pressure
control. 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.

- Type 41 |
|
The Bellofram Type 41 regulators
are designed for applications requiring high flow
capacity, low droop, high accuracy, and fine adjustment
sensitivity. The use of Bellofram's pre-convoluted
rolling diaphragm provides greater sensitivity and
improved accuracy from a constant effective area.
In addition, Type 41 regulators offer reduced over-all
size and new mounting options, providing direct interchangeability
with more expensive units available in the industry.
|
|
|
Ruggedly designed and constructed, the Bellofram
Type 41 regulators have housings
of precision-cast aluminum. They are pressure tested,
and are chromate treated for 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 to panel applications due to ease of mounting,
small size, adjustment sensitivity, and standard knob.
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 mounting packages.

- Type 70 High-Flow Pressure |
|
The Bellofram Type 70 Regulator is
specifically designed for applications that require
substantial flow capacity and accurate pressure controls.
Flows of 80 SCFM can be attained. Downstream pressure
can be set within 0.25" of water column and is accurately
maintained under varying flow conditions with the
help of an aspirator tube which adjusts the air supply
in accordance with the flow velocity. A balanced supply
valve, utilizing a rolling diaphragm, makes the regulator
virtually immune to changes in supply pressure.
|
|
|
|
Careful design and quality materials throughout assure
long, trouble free operation in the most difficult
industrial environments. The Bellofram
Type 70 has a rugged, precision die-cast
aluminum housing, and is pressure-tested and chromate-treated
for corrosion resistance. The regulator housing is
finished with vinyl paint, which resists scratching,
weathering and other physical abuse. |
|
The Bellofram Type 70
is also available in a back-pressure model, the Type
70BP Back-Pressure Regulator functions as a high flow,
high precision pneumatic relief valve with an adjustable
set point. Back flows of up to 50 SCFM can be attained.
A sensitive Bellofram rolling diaphragm is the key
component in making this regulator extremely responsive
to slight upstream pressure changes. Stack-up construction
makes the regulator easily serviceable, without removing
it from the air line. |

- Type 77 Vacuum |
|
Bellofram's
Type 77 Vacuum Regulator incorporates a fixed
negative 15 psig bias spring to maintain vacuum outputs
up to 29" Hg. An adjustable opposing range spring
increases controlled pressure outputs up to 150 psig.
Output pressure droop under varying downstream flow
conditions is minimized by use of an aspirator tube
which adjusts the air supply valve opening in accordance
with flow velocity. A balanced supply valve, utilizing
a reinforced rolling diaphragm, keeps regulator output
virtually immune to changes in supply pressure. Stack-up
construction makes the Type 77 easily serviceable,
without removing it from the air line. |
|
|
|
|
|
Applications
The Bellofram
Type 77 provides precise control
in sub atmospheric pressure applications. specific
uses include sample collecting systems, air quality
monitoring, parts coating operations, and other industrial
functions requiring controlled system pressure from
29" Hg vacuum to 150 psig. |
|
Features
|
 |
Single-unit
control of pressures from 29" Hg vacuum to 150
psi. |
|
Flow
capacity up to 40 SCFM. |
|
Dampening
action of aspirator tube maintains stable output pressure.
|
|
Output
virtually unaffected by changes in supply pressure.
|
|
Can
be disassembled and service without removing from
line. |
|
Operation
The regulator
may be installed either upstream or downstream from
the vacuum pump. Upstream installation is preferred
when rapid evacuation of a vessel or system is required,
because the exhaust capacity of the pump is normally
greater than that of the regulator. In all other applications,
the regulator can be located between the pump and
the vessel. When the adjustment knob is turned to
create an output set point, the range spring exerts
a downward force on the signal diaphragm, which causes
the supply valve to open. Output pressure, combined
with the negative bias spring, creates an upward force
on the diaphragm assembly. When the set point is reached,
the two forces are in balance. If output pressure
exceeds the set point, the excess pressure is transmitted
through the aspirator tube to the bottom of the control
diaphragm. This moves the diaphragm assembly upward,
closing the supply valve. Excess output pressure is
vented until the set point is again reached.

- Type 78 High Flow Precision Air |
|
The Bellofram Type 78
High Flow Precision Air Regulator is designed for
applications where precise control of flow is needed.
This regulator offers low droop, high accuracy, and
fine adjustment sensitivity. The use of a Bellofram
rolling diaphragm provides greater sensitivity and
improved accuracy. In addition, the Type 78 offers
a balanced pintle, which minimizes output pressure
changes caused by fluctuations in supply pressure.
Careful design and quality materials throughout assure
long, trouble-free operation. The rugged die-cast
zinc and aluminum housings are pressure tested to
assure safe operation, and are designed to withstand
harsh and abusive environments. This durability is
attributed to a chemical conversion coating of all
cast components, and a vinyl paint finish. With a
supply pressure of up to 400psig and output ranges
up to 125 psig, the Type 78 can achieve flow rates
of well over 200 SCFM. |
