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
forgoing 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.
All Controlair Valves utilize a pipe bracket. Piping
connections made to the pipe bracket need not be disturbed
when removing the operator portion for maintenance.
The H-1 Controlair Valves are designed for floor mounting;
the complete assembly is installed and removed from the
top of the floor. The valve extends beneath the floor. Refer
to page 3 & 4 for panel opening dimensions. Allow suitable
clearance for pipe bracket cap screws which are 1 ¾” long.
H-1-A Controlair Valve is mounted directly to a floor
platform by two bolts through the lugs in the pipe bracket.
The floor, or platform normally serves as a stop for the
pedal. Refer to installation view on page 5 for panel opening
dimensions. Allow suitable clearance for pipe bracket
screws which are 1 ¾” 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
routine 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, pages 12 & 13,
and Test Procedures, page 14.
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 four (4) screws and lift
the unit free.
No special tools are required to maintain the Controlair
Valve.
