For the pneumatic center position, the air connections
C
and
D
must be actuated together with a branching.
Variant with locked
center position (VM)
If supply air throttle valves are used with the locked center
position on the air connections
C
and
D
, the locking is engaged
smoothly. The operating pressure for the lock must be between 4

center position, this can cause malfunctions.
