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.
