A valve includes a device for shutting off a valve interior. The shutoff device is positioned by a piston which is guided in a cylinder and forms a first chamber and a second chamber in the cylinder. The second chamber communicates with the valve interior through a throttle path, so that the shutoff device is movable in a damped manner in both closing and opening directions.

Damped valve

A steam power station, in particular a nuclear power station, includes a steam conduit leading through a wall and forming a fixed point with the wall for the introduction of forces and moments. A main valve is connected to the steam conduit at the fixed point, without a high-pressure pipe being interposed. Satellite valves, which have smaller nominal widths than the main valve, are fastened to the housing of the main valve, without a high-pressure pipe being interposed. At least one additional valve has a housing fastened to the housing of a satellite valve, without a high-pressure pipe being interposed and without any support.
