Abstract
A hydraulic valve arrangement () is provided comprising comprising a supply port arrangement having a high pressure port () and a low pressure port (), a working port arrangement having two working ports (), a first valve () arranged between said high pressure port () and said working port arrangement (), a second valve () arranged between said low pressure port () and said working port arrangement (), a controller () for controlling said first valve () and said second valve (), said controller () having an input connection () for receiving a signal of an operator input device, and a regenerative flow path which can be established by means of at least one of said first valve () and said second valve (). The function of such a hydraulic valve arrangement should be enhanced. To this end said controller () said controller interrupts said regenerative flow path when a feed pressure at said working port arrangement () exceeds a predetermined pressure level.
