Type code

Notices:

• Stroke adjustment should only be used with reduced operating pressure.

• In case of mechanical blocking of the "closed" position, the spring chamber of the screw-in cartridge valve should be continuously supplied with pilot pressure. This way, the control spool of the screw-in cartridge valve is hydraulically pressed into basic position and the stroke adjustment provides additional mechanical protection against opening.

• If the screw-in cartridge valve is not hydraulically supplied in a mechanically closed position, the forces acting in opening direction may cause slight leakage at the seat due to settlement and despite mechanical clamping.

• A mechanically blocked "closed" position should either be released in depressurized condition or with a pressurized spring chamber to enable release of the adjustment spindle with reduced force.

• Nozzle fitting for adjustment of the actuating time must be realized in the block. Arrangement of two nozzles with sufficient distance in between is recommended.

• For further information on nozzles, see "Accessories".
