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".
