Abstract
A valve arrangement is provided for selectively connecting a source of fluid pressure to a consumer in order to actuate the consumer in a predetermined direction. The valve arrangement utilizes a valve cone arranged in the valve body which connects the valve ports with each other when the valve cone is in its open position, and is actuated by a holding force which is greater than the force acting on the pressurized fluid side of the valve cone and dependent on the medium pressure in the input port.
