FUNCTION:
HYDAC 4/2 directional spool valves
in the series 4WE 6 D 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.

The operating limit was determined with warm coil and an undervoltage
of
10%. The specified operating limit is only valid for use with two flow
directions (e.g. flow from P to A and simultaneous flow from B to T).
Here see specific valve symbol. Using only one flow direction may
reduce the operating limit.
By operation with G96/G205 coil the max. flow rate has to be reduced
by 10%. The Switch-on time will increase.
