FUNCTION:
HYDAC 4/2 directional spool valves
in the series 4WE 6 QA are
directional valves for oil- hydraulic
systems, which serve to open and
close flow paths. In the de- energised
mode the control spool is held in the
rest position by the return spring. The
actuation of the control spool occurs
via an oil- immersed solenoid. The
solenoid pushes the control spool
from its rest position to its final
position. This opens the required flow
paths according to the symbol. When
the solenoid is de- energised, the
control spool is pushed back to the
rest position by the return spring. A
manual override permits the valve to
be switched without energising the
solenoid.
