Notices!

Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for the operation, separate order, material no. R900024943). When the manual override is blocked, the actuation of the solenoid must be prevented! The simultaneous actuation of the solenoids must be prevented!

Stroke setting on side A and B	94	248
Stroke setting on side A	94	-
Stroke setting on side B	-	248

The stroke of the main spool is limited by the stroke setting.

The piston stroke is shortened by untightening the lock nut (19) and clockwise rotation of the adjustment spindle (20). For this, the control chamber has to be depressurized.

Stroke 9.5 mm (1 rotation = 1.5 mm stroke)

Throttle insert

Use of the throttle insert (10) is necessary if the pilot oil supply in channel P of the pilot control valve is to be limited.

The throttle insert (10) is inserted in channel P of the pilot control valve.
