The spring device urges the actuating means into the open position or into the closed position. Further, the spring device includes a plurality of springs and a receiving unit for the springs. Here, each spring has its own spring chamber formed in the receiving unit, in which the associated spring is inserted. Furthermore, a valve having such a valve linear drive is provided.
