In circuits with unloaded pump circulation the internal pilot pressure is not sufficient. The H-4WEH25T6X/6EG24TK4QM0G24/P4,5 therefore takes pilot oil externally and returns it internally, at up to 400 l/min and 350 bar maximum operating pressure.

Applications
Typical for press and steel plant applications with pump circulation in the rest position, where the valve still has to shift reliably. Pilot oil comes from a supply of its own, such as the power unit pilot line. The return stays internal and saves one line.
