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).
