Abstract
A hydraulic valve device has a fluid port arrangement (10) with various ports extending at least partially in the valve housing (14), and has a movable control device (18) for at least partially activating the ports. The control device (18) can be acted on at two opposite control sides with a control pressure (XA, XB) of an activation unit (46). A valve device of narrow construction and functionally reliable is created by a media-conducting duct (66) with a guide path extending at least partially as an open duct channel that can be closed off by a cover part or by other housing parts of the multi-part valve housing (14), to conduct the control pressure (XB) from the activation unit (46) to the assignable control side of the control device (18).
