Auxiliary spool valve
H . 4-position DA spool valve, with
automatic return to neutral and floa-
ting position
Operation (Fig. 15)
When the spool (2) is moved upwards or downwards,
the same positions are obtained as in the previous
spool valves.
The 4-position DA spool valve with automatic return to
neutral and floating position has an added feature: a
floating position (F) when the spool has moved its
maximum distance out of the automatic return to
neutral position (Fig. 16).
In this position (F), the outlet channels (A) and (B) open
into the return channel (R). The oil then circulates
freely.
