Abstract

The module (M) has two main stage-elements (E1, E2) controlled by load pressure and connected in series in an outflow path (9), where the stage-elements are supplied with sealing pressure in a direction of a shut-off position. Pressure is derived from the load pressure by a throttle (16). The elements are commonly controlled in parallel by a magnetic servo valve (21) that is arranged in a sealing pressure-control line (20) that is shielded to a lifting hydraulic motor (Z), load pressure and a lifting section (1) by the throttle.
