______________________________________
“
D” PILOTAIR Valves are spool type directional
valves with two-way, three-way or four-way
operation. They are built with open exhaust
ports and with tapped exhaust ports. With
different valve stems the three-way and four-
way valves may have a mid-position where all
ports are lapped, supply is connected to
delivery or delivery is connected to exhaust.
Lever, button, pedal, treadle, cam pilot cylinder
or solenoid operates the “D” PILOTAIR Valve.
These operators may be put on either end or
both (see OPERATION). The operator may
have springs to return the valve system to its
normal position when the operating force is
removed.
WARNING - INSTALLATION AND
MOUNTING
The user of these devices must con-
form to all applicable electrical, me-
chanical, piping and other codes in the installa-
tion, 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
systems and devices, or under trained
supervision.
Compressed air 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 the
pressure from an air 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
Mount the “D” PILOTAIR Valve on a solid flat
surface by means of the mounting holes in the
body. Do not support the valve by piping alone.
It may be installed in any position. When
installed vertically, protect the end of the valve if
there is danger of dirt or moisture falling into it.
Connect the port in the body of solenoid
operators to an air supply not exceeding 150 psi
(10 Bar). The pilot cylinder operator contains a
1/32” choke for air operation.
Identify passages through the valve and label
ports before installation. To facilitate installation,
each port, each end bracket and the operator can
be rotated in 90° steps around the stem by
removing the tie rods and turning the section. Do
not make a modification unless it is absolutely
necessary. All modifications should be made on
a clean bench to insure that dirt does not enter
the valve.
ADJUSTMENT
The “D” PILOTAIR Valve requires no adjustment.
