SM-800.6516 H4 Controlair

H-4 CONTROLAIR® VALVE
Service Information
DESCRIPTION OF MODELS
The H-4 Type CONTROLAIR Valves are knob
operated 3-way pressure graduating valves. The knob
actuates the pressure graduating portion to increase,
decrease or maintain graduated air pressure to a
separate delivery line.
In knob “release” position the delivery line is connected
to exhaust. Knob rotation from release position
actuates the graduating portion to deliver graduated
pressure to a delivery line according to the value of
control spring being used. The knob is self holding in
all positions.
The H-4 CONTROLAIR Valve is available with either
clockwise rotation or counterclockwise rotation of the
knob increasing pressure.
WARNING: INSTALLATION AND
MOUNTING
The user of these devices must conform to all applicable
electrical, mechanical, piping and other codes in the
installation, operation or repair of these devices.
INSTALLATION! Do not attempt to install, operate or
repair these devices without proper training in the
technique of working on pneumatic or hydraulic systems
and devices, unless under trained supervision.
Compressed air and hydraulic systems contain high
levels of stored energy. Do not attempt to connect,
disconnect or repair these products when a system is
under pressure. Always exhaust or drain the pressure
from a system before performing any service work.
Failure to do so can result in serious personal injury.
MOUNTING! Devices should be mounted and
positioned in such a manner that they cannot be
accidentally operated.

Installation and General Maintenance Recommendations
Installation
General Maintenance
Before installing the Controlair® Valve, all air lines in
the system should be blown clean to remove any
moisture, dirt, or harmful contamination. Strainers are
furnished in the Inlet and Outlet ports to protect the
valve from large particles of foreign matter in the line.
To further ensure long, trouble-free service, a 10
Micron or better filter should be installed in the supply
line to the valve.
Maintenance periods should be scheduled in
accordance with frequency of use and working
environment of the Controlair Valve. All valves must
be visually inspected for wear and given an “in
system” operating performance and leakage test at
least once a year. If these visual observations
indicate valve repair is required, the valve must be
removed, repaired and tested.
The H-4 type Controlair is designed for either side or
panel mounting, and may be mounted in any position
convenient for operation. Refer to installation view,
page 3, for panel thickness and opening dimensions.
Allow suitable clearance for removal of the pipe
bracket screws which are 1 ¾” (44 mm) long.
A major overhaul is recommended at one million
cycles. However, where frequency of use is such that
it would require more than two years to obtain one
million cycles, the valve must be overhauled at the
two-year period.

When it is determined that the Controlair Valve
requires a major repair as a result of the one million
cycles, one year routing inspection, or the two year
service period has elapsed, the device must be
disassembled, cleaned, inspected, parts replaced as
required, rebuilt and tested for leakage, and proper
operation prior to installation. Refer to MAJOR
REPAIR AND MAINTENANCE INSTRUCTION, page
9, and TEST PROCEDURES, page 10.
One complete Controlair Valve should be kept in
stock for each four valves in service. During the
maintenance period, replace the complete valve with
the “stand-by” unit. This will reduce production time
loss and afford inspection and replacement of worn
parts at a more appropriate or opportune time and
favorable location.
Notice that the operating portion of a valve can be
removed without disturbing the pipe connections.
Remove the valve from the pipe bracket by loosening
(2) screws and lift the unit free.
No special tools are required to maintain the
Controlair Valve.

DESCRIPTION OF OPERATION
VALVE
FUNCTION
Exhaust
Outlet
Inlet
Description of Operation
When the knob is in released position, the “IN” port is
closed to supply pressure and “OUT” port is open to
exhaust.
Note in the diagrammatic, when the knob is rotated to
increase pressure, the shaft and cam are also rotated. The
rotation of the knob allows the cam to push down the
pressure control plunger, closing the lower exhaust valve
and opening the upper supply valve which permits air flow
to out port delivery and the upper diaphragm chamber. As
the pressure builds up in the delivery line it acts through
the sensing port orifice and deflects the control diaphragm
downward, compressing the control spring. When sufficient
diaphragm deflection is reached to allow the upper supply
valve in the pressure control portion to close, the pressure
in the delivery line is held to that valve. The valve of the
pressure delivered to the outlet port is proportional to the
pressure control plunger movement. This movement in turn
is controlled by the cam contour and is therefore
proportional to the knob travel.
The Controlair Valve will automatically compensate for
downstream air pressure changes in the graduated
pressure delivery line. These air pressure changes can be
caused by line leakage, temperature change or load
feedback. If air pressure at the outlet port increases over
that called for by handle position, the diaphragm in the
control portion will deflect downward opening the lower
exhaust valve and exhausting air until the original setting is
obtained. If the pressure drops below that called for by the
handle position, the decreased force on the diaphragm will
allow the control spring to force the diaphragm upward,
opening the upper supply valve to restore the set pressure.
The range of pressure is controlled by the strength of the
diaphragm spring. Various values are available as shown
on Identity Schedule, page 5.

Repair and Maintenance Instructions
Repair and Maintenance Instructions
When it has been determined that the Controlair®
Valve requires repairs, the following general
instructions are recommended.
Adjustments
There is one adjustment that can be made to the H4 Controlair Valves. This is the adjusting screw item
#1, that varies the output pressure.
Disassembly, Cleaning and Lubrication
Completely disassemble the Controlair valve. Wash
all metal parts in a non-flammable solvent. Rinse
each part thoroughly and blow dry with low
pressure air.
Graduated Output Pressure Adjustments
Adjusting screw Item #1 varies the maximum
pressure setting. Turning the adjusting screw “in”
raises the maximum pressure. Turning the screw
“out” decreases the maximum pressure. The
maximum control pressure adjustment should not
exceed the maximum control pressure shown in the
Identity Schedule for that part number. (Control
Springs are color coded).
Inspect and clean the inlet filter Item #17 and both
gaskets Item #18. Be sure all passages in the body
and pipe bracket and sensing port orifice in top of
the diaphragm chamber are clean and unrestricted.
Examine all parts carefully. Replace all rubber parts
and all worn or damaged parts. The use of repair
kits is recommended.
Reassemble
Refer to exploded Parts and Assembly Views.
Valves should always be reassembled using new
rubber parts.
Lubricate all metal to metal wear surfaces with
Lubriplate 107 Grease. Lubricate all the rubber
parts, except the diaphragm with Dow Corning
No. 55 Pneumatic Grease.
The maximum output pressure rating can be
changed by changing the control spring Item #5.
With air supplied to the valve, move handle from
start to full travel position. Adjust graduating valve
screw Item #1 to obtain the maximum control
pressure per Identity schedule. Move handle back
to neutral position and note delivery line is
exhausted to zero.
Special Preload Setting
This setting calls for a predetermined delivery
pressure.
The exhaust valve and seat if not replaced should
be polished for minimum leakage using a 600 grit
lapping compound. Be sure to clean these parts
prior to installing in the valve.
Installing the knob (Item #33a), seat the knob on
the shaft, Item #25 before installing the set screw,
Item #33b.
Do not over torque the set screw.

Testing and Test Set-Up (See Test Arrangement Diagram)
Testing
After any repair or adjustments, the H-4 Controlair®
Valve should be tested using the following procedures
and test arrangements described in this section.

need to be tested for the
Flow Capacity
Response
Mechanical Detents
The adjustments affecting these points were described
in the previous sections.
General instructions for accomplishing these tests are
listed below.
1. Function: The H-4 Controlair Valves are rotary
actuated 3-way pressure graduating valves.
Rotating the knob actuates the valve to increase,
decrease or maintain graduated air pressure to the
“OUT” port or delivery line.
2. Pressure Range: Supply pressure at “IN” port will
be delivered as graduated pressure to the “OUT” or
delivery port depending upon the range of the
control spring being used and the handle position.
The handle in the “OFF” or returned position the
“OUT” or delivery port is at minimum pressure
setting. Moving the handle actuates the graduating
c on tr ol
p or t i on
to
de l i ve r
gr ad u at ed
pressure to the “OUT” or delivery port. Check the
valve to confirm the Minimum Pressure of 30 psi
(2 Bar) and Maximum pressure of 70 psi (4.9
Bar).
3. Leakage: Set supply pressure to 20 psi (1.4 Bar)
above maximum delivery pressure of the valve
being tested. Using soap and water solution, coat
the valve at the pipe bracket and spring housing
parting lines. No leakage is permitted in any handle
position.
A. Port (IN)
1. On all valves with spring ranges less than 90
psi (6.2 bar), set supply line pressure to 100 psi
(6.9 bar). Move handle to full travel position
and hold (detent position on detented valves).
Close valve in supply line to “IN” port or
delivery line to isolate graduating valve.
Observe delivery pressure gage in line. A
pressure drop of no more than 2 psi (0.14 bar)
in 30 seconds is permitted.
4. Flow Capacity: Set supply line pressure to 100 psi
(6.9 bar) regardless of the control spring rating.
Moving the handle from “OFF” position to the full
travel position, the delivery volumes should start to
fill within the time limits shown in Table 1.
Move the handle quickly from full travel position to
back to “OFF” position. This should exhaust
volumes within the time limits shown on table 1.
Note: valves with less than 0 to 35 psi (2.4 bar) or
less rated springs require an additional volume as
shown in test arrangement diagram.
5. Response: Rotate the knob to full travel position
and hold. Fully open the valve at test volume so
that that the air exhausts through the choke plug.
Observe the delivery pressure gage at volume (1).
A pressure drop of no more than 3 psi (0.2 Bar) is
permitted.

NOTICE TO PRODUCT USERS
1. WARNING: FLUID MEDIA
AVENTICS pneumatic devices are designed and tested for use with
filtered, clean, dry, chemical free air at pressures and temperatures within
the specified limits of the device. For use with media other than air or for
human life support systems, AVENTICS must be consulted. Hydraulic
cylinders are designed for operation with filtered, clean, petroleum based
hydraulic fluid; operation using fire-resistant or other special types of fluids
may require special packing and seals. Consult the factory.
2. WARNING: MATERIAL COMPATIBILITY
Damage to product seals or other parts caused by the use of
noncompatible lubricants, oil additives or synthetic lubricants in the air
system compressor or line lubrication devices voids AVENTICS warranty
and can result in product failure or other malfunction. See lubrication
recommendations below.
AIR LINE LUBRICANTS! In service higher than 18 cycles per minute or
with continuous flow of air through the device, an air line lubricator is
recommended.* (Do not use line lubrication with vacuum products.)
However, the lubricator must be maintained since the oil will wash out the
grease, and lack of lubrication will greatly shorten the life expectancy. The
oils used in the lubricator must be compatible with the elastomers in the
device. The elastomers are normally BUNA-N, NEOPRENE, VITON,
SILICONE and HYTREL. AVENTICS recommends the use of only
petroleum based oils without synthetic additives, and with an aniline point
between 180° F and 210° F.
COMPRESSOR LUBRICANTS! All compressors (with the exception of
special "oil free" units) pass oil mist or vapor from the internal crankcase
lubricating system through to the compressed air. Since even small
amounts of non-compatible lubricants can cause severe seal deterioration
(which could result in component and system failure) special care should
be taken in selecting compatible compressor lubricants.
3. WARNING: INSTALLATION AND MOUNTING
The user of these devices must conform to all applicable electrical,
mechanical, piping and other codes in the installation, operation or repair
of these devices.
INSTALLATION ! Do not attempt to install, operate or repair these
devices without proper training in the technique of working on pneumatic
or hydraulic systems and devices, unless under trained supervision.
Compressed air and hydraulic systems contain high levels of stored
energy. Do not attempt to connect, disconnect or repair these products
when a system is under pressure. Always exhaust or drain the pressure
from a system before performing any service work. Failure to do so can
result in serious personal injury.
MOUNTING! Devices should be mounted and positioned in such a
manner that they cannot be accidentally operated.
4. WARNING: APPLICATION AND USE OF PRODUCTS
The possibility does exist for any device or accessory to fail to operate
properly through misuse, wear or malfunction. The user must consider
these possibilities and should provide appropriate safe guards in the
application or system design to prevent personal injury or property
damage in the event of a malfunction.
5. WARNING: CONVERSION, MAINTENANCE AND REPAIR
When a device is disassembled for conversion to a different configuration,
maintenance or repair, the device must be tested for leakage and proper
operation after being reassembled and prior to installation.
MAINTENANCE AND REPAIR! Maintenance periods should be
scheduled in accordance with frequency of use and working conditions. All
AVENTICS products should provide a minimum of 1,000,000 cycles of
maintenance free service when used and lubricated as recommended.
However, these products should be visually inspected for defects and
given an "in system" operating performance and leakage test once a year.
Where devices require a major repair as a result of the one million cycles,
one year, or routine inspection, the device must be disassembled,
cleaned, inspected, parts replaced as required, rebuilt and tested for
leakage and proper operation prior to installation. See individual catalogs
for specific cycle life estimates.
6. PRODUCT CHANGES
Product changes including specifications, features, designs and
availability are subject to change at any time without notice. For critical
dimensions or specifications, contact factory.
*Many AVENTICS pneumatic valves and cylinders can operate with or
without air line lubrication; see individual sales catalogs for details.
--Refer to the appropriate service catalog for parts and service information.
LIMITATIONS OF WARRANTIES & REMEDIES
AVENTICS warrants its products sold by it to be free from defects in material and workmanship to the following:
For twelve months after shipment AVENTICS will repair or replace (F.O.B. our works), at its option, any equipment which under normal
conditions of use and service proves to be defective in material or workmanship at no charge to the purchaser. No charge will be
made for labor with respect to defects covered by this Warranty, provided that the work is done by AVENTICS or any of its authorized
service facilities. However, this Warranty does not cover expenses incurred in the removal and reinstallation of any product, nor any
downtime incurred, whether or not proved defective.
All repairs and replacement parts provided under this Warranty policy will assume the identity, for warranty purposes, of the part
replaced, and the warranty on such replacement parts will expire when the warranty on the original part would have expired. Claims
must be submitted within thirty days of the failure or be subject to rejection.
This Warranty is not transferable beyond the first using purchaser. Specifically, excluded from this Warranty are failures caused by
misuse, neglect, abuse, improper operation or filtration, extreme temperatures, or unauthorized service or parts. This Warranty also
excludes the use of lubricants, fluids or air line additives that are not compatible with seals or diaphragms used in the products. This
Warranty sets out the purchaser's exclusive remedies with respect to products covered by it, whether for negligence or otherwise.
Neither AVENTICS nor any of its affiliates will be liable for consequential or incidental damages or other losses or expenses incurred
