GENERAL MAINTENANCE AND REPAIR
RECOMMENDATIONS
Maintenance periods should be scheduled in accordance
with frequency of use and working environment of the Con-
trolair Valve.
All valves must be visually inspected for wear and given an
“In System” operating performance and leakage test at least
once a year. If these visual observations indicate valve repair
is required, the valve must be removed immediately and
repaired.
A major overhaul is recommended at one million cycles.
However, where frequency of use is such that it would re-
quire more than two years to obtain the one million cycles,
the valve must be overhauled every two year period.
When it is determined that the Controlair Valve requires a
major repair as a result of the one million cycles, one year
routine inspection or the two year service period has
elapsed, the device must be disassembled, cleaned, inspect-
ed, parts replaced as required. The valve then must be test-
ed for leakage and proper operation prior to installation, refer
to the Major Repair and Maintenance Instructions and test
procedures.
Notice that the operating portion of the valve can be re-
moved without disturbing the pipe connections by just re-
moving the (2) screws that hold the pipe bracket to the valve.
No special tools are required to maintain the Controlair
valves.
One complete Controlair valve should be kept in stock for
every (4) valves in service. During the maintenance period,
replacing the complete valve with the stand-by unit reduces
production down time and affords inspection and replace-
ment of parts at a more appropriate time and favorable loca-
tion.
WARNING: INSTALLATION
AND MOUNTING
The user of these devices must conform to all appli-
cable electrical, mechanical, piping and other codes
in the installation, operation or repair of these devic-
es.
INSTALLATION! Do not attempt to install, oper-
ate or repair these devices without proper train-
ing 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 ex-
haust 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 and General Mainte-
nance Recommendations
Before installing the Controlair Valve®, all air lines in
the system should be cleaned to remove all dirt,
moisture or contamination.
A strainer is furnished on the inlet port to protect the
valve from large particles or foreign matter in the
supply line. To insure long, trouble-free service, a 10
micron or better filter should be installed in the sup-
ply line to the valve.
The H-2 Controlair Valve is designed for panel
mounting. The valve less the pipe bracket can be
installed from the top of the panel. Refer to the in-
stallation view on pages 3 & 4 for panel opening
dimension. Allow suitable clearance for installing or
removing of the (2) pipe bracket screws which are 1
1/2” (38 mm) long.
