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.

 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 Inlet & Exhaust
the pressure builds up in the delivery line it acts through Valve Unit
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 Supply Valve
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 Exhaust Valve

downstream air pressure changes in the graduated
pressure delivery line. These air pressure changes can be
caused by line leakage, temperature change or load Diaphragm
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 Range Control
exhaust valve and exhausting air until the original setting is Spring
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 Exhaust Port Adjusting Screw
on Identity Schedule, page 5.

The H-4 Controlair is factory set to provide normal 240

degree rotation of the control knob. However, the 240-
degree rotation can be reduced by changing the DIAGRAMMATIC VIEW
relationship of the stop with the cam brake.

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
by reason of the use or sale of such products. Our liability (except as to title) arising out of the sale, use or operation of any product or
parts, whether on warranty, contract or negligence (including claims for consequential or incidental damage) shall not in any event
exceed the cost of replacing the defective products and, upon expiration of the warranted period as herein provided, all such liability is
terminated. THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WHETHER FOR
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE. No attempt to alter, amend or extend this
Warranty shall be effective unless authorized in writing by an officer of AVENTICS Division.
AVENTICS reserves the right to discontinue manufacture of any product, or change product materials, design or specifications without
notice.
