Rohrbruchsicherung Regeneration
Lifting and lowering the operator’s cab often places high demands on the comfort function. Smooth starting and braking are required, as is leakage-free holding in the raised position. The cab control is a 4/3 directional control valve designed to operate on a fixed displacement pump. The integrated inlet pressure compensator reduces pressure losses to a minimum. The main spool can be adjusted electrically-proportionally, and an internal circuit imposes a ramp on the spool when switched. Output A is locked leak-free by a pilot-operated check valve.
The LHB-3R type pipe rupture protection has an internal regeneration circuit. The returning volume flow is accumulated by an internal non-return valve and directed to the rod side as required. This allows the cylinder to be retracted without the need for a pump flow rate More Informationen
