  • Patent number: 9534702
    Abstract: Electrohydraulic pilot control means (1) for a hydraulic device which can be a proportional directional valve, an adjusting pump or an adjusting motor, which pilot control means contains two proportionally acting pressure control valves (3) and is provided with a control block (2) which accommodates the hydraulic valve parts (4) in holes and to which the associated proportional magnets are flange-connected, wherein the proportional magnets have a common electrical plug connection (5) and wherein the two proportional magnets (3) are joined to form an assembly by being encapsulated with plastic, the said assembly being fastened to the control block (2) and, in this case, being precisely oriented relative to the valve components (4), which are accommodated in the control block, by means of positioning aids which act perpendicular to the movement direction of armatures.
