FUNCTION:
HYDAC 4/2 directional spool
valves in the series 4WE 6 D-OF
are directional valves for oil-
hydraulic systems, which serve to
open and close flow paths. The
4WE 6 D-OF is a directional valve
with two spool positions, two
solenoids and one detent. It
alternately locks the two spools in
position. Therefore the solenoid
needs not to be permanently
energized.

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.
