Aventics CONTROLAIR H-4 Service Information

DESCRIPTION OF MODELS

The H-4 Type CONTROLAIR Valves are knob
operated 3-way pressure graduating valves. The knob
actuates the pressure graduating portion to increase,
decrease or maintain graduated air pressure to a
separate delivery line.
In knob "release" position the delivery line is connected
to exhaust. Knob rotation from release position
actuates the graduating portion to deliver graduated
pressure to a delivery line according to the value of
control spring being used. The knob is self holding in
all positions.
The H-4 CONTROLAIR Valve is available with either
clockwise rotation or counterclockwise rotation of the
knob increasing pressure.
