H-3, H-3-G & SH-3 CONTROLAIR
DESCRIPTION OF MODEL
The H-3 TYPE CONTROLAIR Valves are 3-way
pneumatic pressure graduating valves. The operator
portion is equipped with a cam roller which can be
operated by another cam or similar mechanical
operator. The roller actuates the pressure graduating
potion to increase, decrease, or maintain graduated air
pressure to a separate delivery line.
In "release" position the delivery line is connected to
exhaust, except preload type. From "release" position,
force down on the roller actuates the graduating portion
to deliver graduated pressure to a delivery line
according to the value of control spring being used.
The roller is spring returned from all positions.
WARNING: INSTALLATION AND
MOUNTING
The user of these devices must conform to all applicable
electrical, mechanical, piping and other codes in the
installation, 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 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 exhaust 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.
