SERVICE INFORMATION

BLOCK TYPE: Pages 1-6
PANEL MOUNTED: Pages 7-22

The Block Type “A” PILOTAIR Valve is a poppet

type, on-off, three-way directional valve. The body
design lends itself to individual or multiple
mounting operations. The basic valve 2-MA-1A,
with a choice of six operators, can be easily and
quickly assembled without special tools. The valve
is interchangeable with the former design. Refer to
“Identity Schedule,” page 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.

Installation (BLOCK TYPE)

The Block Type “A” PILOTAIR Valve can be installed in

any convenient position without interfering with the valve
operation. The straight, flat sides are identical to provide
either right or left hand horizontal mounting. Mounting
holes are also provided for mounting the valve vertically
from the top or bottom.

Dual IN and OUT ports are provided on all valves
except the 2-CA-1B for ease of piping. Pipe plugs
are supplied for plugging the unused ports.

Note: Install the valve to ensure operation within the
travel limits shown on the outline drawings (refer to
sales catalog SC-700-800). Travel beyond these
limits can cause damage to the valve plunger O-ring
and subsequent valve leakage.

Operation

The Block Type “A” PILOTAIR Valve is designed

to operate at pressures up to 250 psi within a
temperature range of -40º F to 200º F (-40° C
to 93° C).

MOUNTING! Devices should be mounted and
positioned in such a manner that they cannot be
accidentally operated.

AVENTICS “A” PILOTAIR® VALVE SERVICE INFORMATION

FIGURE 1: Block Type PILOTAIR Valve
Assembly View.

Refer to Figures 1 and 2. With no mechanical
force on the plunger as shown, the valve disc
seats on the inlet valve seat and seals the pas­sage from the inlet to the outlet port. The outlet
port is vented to atmosphere through the center of
the plunger. As the plunger is forced downward by
an external force it seats on the valve disc. This
seals the passage between the outlet port and
atmosphere.
Further downward travel of the plunger unseats
the valve disc from the inlet valve seat and allows
inlet air pressure to flow to the outlet port.
Release of the external force, releases the
plunger and valve, and plunger return to the
original position.

Install the valve to ensure operation within the
travel limits shown on the outline drawings.
Travel beyond these limits can cause damage to
the valve.

All combinations of the Block Type “A” PILOTAIR
Valve are “normally closed” except that desig­nated 2-CA-1B which is “normally open.”

Maintenance

Disassembly

Refer to Figure 2. Completely disassemble the valve
in sequence shown.

NOTE: Strainers are easily damaged. Do not
remove from IN ports of valve body.

Cleaning

1. Clean the body, with strainers intact, and
all other metal parts with a nonflammable
solvent.

2. Wash all rubber parts with soap and water.

3. Rinse parts thoroughly and blow dry with a
low-pressure air jet.

4. Inspect all parts and replace those which
are worn or damaged.

T H E N E W V A L V E D E S I G N I S
INTERCHANGEABLE WITH THE FORMER
DESIGN.

Reassembly

Refer to Figures 1 and 2, and cartridge valve (4).

1. The valve assembly (4) is a cartridge

PANEL MOUNTED “A” PILOTAIR® VALVE

The Panel Mounted “A” PILOTAIR Valve is a poppet type pneumatic directional control valve consisting of a

cam housing assembly and a valve portion assembled in a variety of configurations.

SEE “WARNING: INSTALLATION AND MOUNTING” ON FRONT COVER.

Latest Design Features

Several features have been designed into the Panel Mounted “A” PILOTAIR Valve for added strength, easier

maintenance and longer service life.

•One-piece solid steel shaft for increased strength

•Bronze bearings in cam housing for longer wear

•Separate steel handle and hub for increased strength

•Tooth-type Nylatron plastic detents for longer wear and more positive detenting

•Internal centering spring assembly for longer wear and more positive handle centering

•One-piece supply valve sub-assembly for easier, more economical maintenance

•Die-cast anodized aluminum body and cam housing for lighter weight, added strength and corrosion

resistance.

•Improved latch

•Simplified “cartridge” repair

Installation

The Panel Mounted “A” PILOTAIR Valve can be mounted in either a horizontal or vertical panel. For

mounting hole dimensions and operator travel, refer to sales catalog SC-700-800.

Operation

The Panel Mounted “A” PILOTAIR Valve is designed to operate at pressures up to 250 psi (17.2 bar) within a

temperature range of -40º F to 200º F (-40° C to 93° C).

Refer to Figure 11. With no mechanical force on the valve disc
seat, the inlet valve seats and seals the passage from the inlet to
the outlet port. The outlet port is vented to atmosphere through
the center of the plunger.
As the plunger is forced downward by the cam force, it seats on
the valve disc. This seals the passage between the outlet port
and atmosphere. Further downward travel of the plunger unseats
the valve disc from the inlet valve seat and allows inlet air
pressure to flow to the outlet port.
Several variations of valve operation and handle holding functions
are available in the Panel Mounted “A” PILOTAIR Valve .

 2-BA-1 PILOTAIR Valve is a two position button

operated valve.

 2-HA-1 PILOTAIR Valve is available with either a two-

position detent or a two-position latching handle.

 2-HA-2 PILOTAIR Valve is available with a two-, three-,

or five-position detent, a latching handle for various
positions, or a spring-centered handle.

Figure 11. Valve Portion

Assembly View

 2-HA-3 and 2-HA-4 PILOTAIR Valves are usually pin-

gated in each handle position, but detents in each
position are also available. A three- or five-position detent
can be supplied on single handle valves if required.

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.

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 wil l 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 Corporation.

AVENTICS reserves the right to discontinue manufacture of any product, or change product materials, design or specifications
without notice.
