Abstract: A pinch valve system includes a closing element arranged in an axial direction and includes a closing piece, a permanent magnetic holding device to hold the closing element by a permanent magnetic force in an open or closed position, without energy being supplied to the permanent magnetic holding device, an electromagnetic actuating device to carrying out a switching process, with which the closing element is configured to be moved from the open position to the closed position or from the closed position to the open position, an energy storage device to store an electrical energy which is sufficient to carry out the switching process, and a controller programmed with a predetermined rest position, which is the open or closed position, and the controller configured to trigger the switching process with which the closing element is brought to the rest position by the energy stored in the energy storage device.
