Vietnam HD-2 Control Air Valve Series

HD-2 control air 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 remainsconnected to atmosphere. Further lever movement in the same direction controls the air pressure delivered by the pressure regulating portion.

HD-2-X CONTROLAIR Valve - The lever returns from the extreme position to the valve’s “Neutral” or “Off” position when the operating force is removed.

HD-2-FX CONTROLAIR Valve - Lever remains in the position where released. Holding friction is adjustable.

HD-2-LX CONTROLAIR Valve - The lever returns to the valve’s “Neutral” or “Off” position when manually moved out of the latch position (extreme travel position).
