Abstract (en)
[origin: DE19548943A1] Disclosed is a valve assembly (8, 10) for the control of a comsumer (1) having two directions of operation, the valve assembly comprising a proportionally acting directional-control valve (12) connected in series with an on/off valve (42) which together control the supply of hydraulic fluid through the outlet of the directional-control valve (12), while a feedback line from the consumer (1) runs through the on/off valve (42) to a hydraulic-fluid reservoir. This enables the hydraulic-fluid supply to be controlled independently of the flow of fluid into the reservoir.
