Abstract
A proportional pressure regulating valve has a valve piston () longitudinally movable in a valve housing () and connecting a utility connection (A) to a pressure supply connection (P) or to a tank or return flow connection (T) dependent on the displacement position of the valve piston. The valve piston is actuated by an actuation magnet () that can be supplied with current. A control device () is between the valve piston () and the actuation magnet (), and allows the valve piston () to become pressureless on the valve piston side () facing the actuation magnet (). The valve piston () is displaced in the direction of the actuation magnet () under the supply and/or utility connection pressure when the actuation magnet is not actuated.
