Abstract
A valve is indicated as well as a device for controlling the valve body in a valve, which is special in that the travel of the valve body in the valve housing is insignificantly damped in the opening movement of the valve, and strongly damped in the closing movement of the valve. The valve is therefore distinguished by the fact that especially in connection with pressure media with a low boiling point, the risk of cavitation in the valve and instability in operation is reduced.
