Abstract (en)
[origin: EP2333351A1] The electro-hydraulic lifting module (M) comprises a magnetic valve device with two 2 by 2-way-magnet seat valves (V1,V2) that are connected in a row in a main line (1) between a supply line (10) and a hydraulic motor (H). One valve is operated by a proportional magnet, and is formed in a flow direction towards a pump (3), where another valve is operated by a black or white magnet (15). A branch line (Z) leads to a pre-control connection (21) of a pressure maintenance valve (D) between the 2 by 2-way-magnet seat valves by the main line.
