Abstract
A hydraulic valve device has a fluid port arrangement () with various ports extending at least partially in the valve housing (), and has a movable control device () for at least partially activating the ports. The control device () can be acted on at two opposite control sides with a control pressure (X, X) of an activation unit (). A valve device of narrow construction and functionally reliable is created by a media-conducting duct () 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 (), to conduct the control pressure (X) from the activation unit () to the assignable control side of the control device ().
