A valve device has a valve housing and a main piston (4) arranged in an axially slidable manner in a piston bore of the valve housing (2). A first consumer connection (A) and a second consumer connection (B) can be alternately connected to a pressure connection (P) and a tank connection (T1, T2) by the action of a first magnetic actuating system (6) and a second magnetic actuating system (8) with two pilot pistons (14, 16). In an actuated state of the respective pilot piston (14, 16), the main piston (4) follows the movement of the pilot piston (14, 16) due to the force ratio adjusting itself to actuate the fluid-carrying connection between the pilot chamber (10, 12) of the pilot piston (14,16) and the assignable tank connection (T1, T2) such that pilot oil flows.
