Abstract

A directional poppet valve (10) has valve pistons (16-22) arranged in a valve housing (12) for controlling a plurality of fluid connections (A, B, P, T). The positions of each valve pistons (16-22) in the valve housing (12) can be changed by at least one actuating device. The fluid connections (A, B, P, T) are connected to one another or separated from one another alternately depending on the position of the valve pistons (16-22). The valve pistons (16-22) are arranged inline along at least one axis (R), consecutively and/or at least such as to partially interengage, in the valve housing (12).
