Instruction and Installation Sheet
PXM
Introduction
Follow these instructions when installing, operating, or
servicing the product.
Installation & Operating Instructions:
The Pilot Exhaust Module (PXM) is installed between an
HA (ISO size 01) valve and a manifold segment. This
valve in conjunction with PXM controls the presence of
14 pilot control pressure in a specific pressure zone in
the manifold. This valve and PXM must be mounted in
the pressure zone.
The pressure zone begins at a segment with the left
gasket pilot ports 12 & 14 blocked. The pressure zone
ends at either the right end plate of the manifold or at the
next segment with the pilot ports 12 & 14 blocked. If a
high flow end plate is the end
of the pressure zone, the
12 & 14 ports must be plugged in the end plate.
Minimum operating pressure of the HA valve on the PXM
must be present in the main pressure galley (port 1) of
the manifold
segment. Valves with pilots controlled in the
pressure zone must be externally piloted to the 14 pilot
port, and 2 position single solenoid valves must have a
spring return mechanism incorporated in the 12 end
return operator. Any valve in this zone configured as
internally piloted or using sandwich regulator will NOT
have their pilot pressure controlled by the PXM.
These conditions will be seen at the externally piloted
valves with solenoids energized and PXM has exhausted
zoned pilot pressure:
•
5/2 Single Solenoid valves (with mechanical
spring) will shift to the 12 position.
•
5/2 Double Solenoid valves will remain in the
“last energized state".
•
5/3 Double Solenoid valves will shift to the
“center position”.
Lubrication
Factory pre-lubed. If lubricating in service, use Parker
F442 oil or equivalent paraffin based mineral oil with 150
to 200 SSU viscosity @100°F.
CAUTION: Do not use oils that are synthetic,
reconstituted, have an alcohol content or a detergent
additive.

These products are intended for use in general purpose
compressed air systems only.
