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.
MOUNTING! Devices should be mounted and
positioned in such a manner that they cannot be
accidentally operated.
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.
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).
BLOCK TYPE “A”
PILOTAIR® VALVE
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.
SM-700.7400

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 pas-
sage 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 desig-
nated 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
design to simplify repairs and eliminate
problems to improper assembly.

AVENTICS “A” PILOTAIR® VALVE SERVICE INFORMATION
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).
PANEL MOUNTED “A” PILOTAIR® VALVE
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.
 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.
