Abstract
A hydraulic valve device, in particular an LS directional valve, includes a housing (), with a pressure supply connection (P), at least one utility connection (A, B), and a load-reporting connection, and includes a controller () moveable in two directions to at least partly actuate fluid those connections. An adjustable stop device () restricts the stroke length of the travel movements of the controller () or parts of the stroke length in either direction. The stop device () has a stop surface () facing in one movement direction and a second stop surface () facing in the other movement direction on the same axial end region () of a slider piston (). A counter stop () is provided for each stop surface (). Both counter stops are on the respective same housing end region () of the housing () in a positionally adjustable manner.
