ABSTRACT:
A two-way control valve includes a valve member with a longitudinal bore connecting its opposite ends with each other. A housing receives the movable valve member and has two attachment ports. A control piston is operatively coupled with the valve member. To provide a two-way valve permitting pressure medium to flow in both directions when the valve member is moved from its closed position, the control piston is tightly or fixedly connected with the valve member and is arranged as an annular collar on the periphery of the valve member. The longitudinal bore is free of constrictions.
