In a valve with pressure control function for common-rail heavy oil injection systems for internal combustion engines, including a valve support, a valve piston movably arranged in the valve support and interacting with a valve seat with the valve closed, and a compression spring applying a compressive force on the valve piston in the closing direction, a pin acting on the valve piston in the closing direction is arranged to be movable by the aid of an actuating means against the compressive force of the compression spring for controllably opening the valve so as to provide a flushing function.
