Installation and General Maintenance Recommendations
Installation
Before installing the Controlair® Valve, all air lines in
the system should be blown clean to remove any
moisture, dirt, or harmful contamination. Strainers are
furnished in the Inlet and Outlet ports to protect the
valve from large particles of foreign matter in the line.
To further ensure long, trouble-free service, a 10
Micron or better filter should be installed in the supply
line to the valve.
The H-4 type Controlair is designed for either side or
panel mounting, and may be mounted in any position
convenient for operation. Refer to installation view,
page 3, for panel thickness and opening dimensions.
Allow suitable clearance for removal of the pipe
bracket screws which are 1 ¾” (44 mm) long.
General Maintenance
Maintenance periods should be scheduled in
accordance with frequency of use and working
environment of the Controlair 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, repaired and tested.
A major overhaul is recommended at one million
cycles. However, where frequency of use is such that
it would require more than two years to obtain one
million cycles, the valve must be overhauled at the
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 routing inspection, or the two year
service period has elapsed, the device must be
disassembled, cleaned, inspected, parts replaced as
required, rebuilt and tested for leakage, and proper
operation prior to installation. Refer to MAJOR
REPAIR AND MAINTENANCE INSTRUCTION, page
9, and TEST PROCEDURES, page 10.
One complete Controlair Valve should be kept in
stock for each four valves in service. During the
maintenance period, replace the complete valve with
the “stand-by” unit. This will reduce production time
loss and afford inspection and replacement of worn
parts at a more appropriate or opportune time and
favorable location.
Notice that the operating portion of a valve can be
removed without disturbing the pipe connections.
Remove the valve from the pipe bracket by loosening
(2) screws and lift the unit free.
No special tools are required to maintain the
Controlair Valve.
