7.7.4 Rotating the solenoid coil by ±90°
Explosion hazard caused by improper assembly!
Improper assembly will result in the loss of the explosion protection!
Strictly observe the following modification instructions for turning the valve
When turning the valve solenoid, make sure that it does not project over the
valve connection surface.
Make sure that the valve solenoid moves freely and does under no circumstance
rest on the base plate.
A gap between valve housing and valve solenoid is not admissible.
Solenoid coils can be assembled in staggered assembly around the pole tube,
i.e. the longitudinal axis of the valve, displaced by ±90°.
The pole tube of the valve solenoid is completely sealed towards the oil circuit.
The solenoid coil can therefore still be twisted if the valve has already been
Detach the mounting nut of the valve solenoid at the pole tube (hexagon nut,
wrench size 32).
Remove the solenoid coil and the O-ring from the valve and rotate it by 90° in the
Re-attach the solenoid coil in the desired position so that the locating pin of the
solenoid coil engages in the corresponding locating hole of the valve housing.
Assemble the O-ring onto the pole tube and slide it forward up to the solenoid coil.
Re-tighten the mounting nut of the valve solenoid (hexagon nut, wrench size 32,
tightening torque 4 + 1 Nm).
