V circuit, negative control
g max
The travel direction valve is pressure spring offset or
switched by energizing switching solenoid a, depending on
the direction of rotation (travel direction).
When the switching solenoid b is energized, the DA control
is overridden and the motor swivels to maximum displace-
ment (high torque, lower speed) (electric V
