The HD-2 CONTROLAIR Valve is a composite lever operated directional valve consisting of two 3-way directional valves and a 3-way pressure regulating portion. Each unit has its own OUT port.

Initial lever movement either side of "Neutral" position activates the OUT port from the pressure regulating portion and one or the other of the ports from the 3-way directional valves. The chosen directional valve port delivers full inlet pressure while the other OUT port remains connected to atmosphere. Further lever movement in the same direction controls the air pressure delivered by the pressure regulating portion.

These valves are used principally to control the forward and reverse clutches and the throttle of an engine. They are also suitable for applications where combined lever-operated direction control arid pressure control are desired.

PIPE CONNECTIONS

Port 1-OUT, full inlet pressure when lever is moved clockwise from "Neutral" (facing lever side of valve).
Port 2-IN pressure.
Port 3-OUT, full inlet pressure when lever is moved counter clockwise from "Neutral".
Port 8-OUT, graduated pressure when lever is moved in either direction from "Neutral".

The lever returns from the extreme position to the valve's "Neutral" or "Off" position when the operating force is removed.

Pressure Range 0 - 100 PSI
