Abstract
A control valve device () for the control of a dual-action consumer () has a control valve () that controls the connection of a pressure fluid line () that forms the admission side of the consumer () with a pump and an additional pressure fluid line () that forms the return side of the consumer () with a reservoir. A regeneration function allows the return side of the consumer () to be connected with the admission side of the consumer (). The regeneration function has a short circuit device () located between the consumer () and the control valve (). For the regeneration function, the connection of the additional pressure fluid line () that forms the return side of the consumer () with the reservoir can be blocked by a shutoff valve device () located between the consumer () and the control valve ().
