Abstract
A pneumatic valve including an air chamber with an air connection, and an actuator with a movable shut-off element and with an SMA element composed of a shape memory alloy. The SMA element is mechanically coupled to the movable shut-off element, wherein, for the activation of the actuator, electrical heating power is fed to the SMA element, after which the SMA element deforms and brings about a predefined movement of the shut-off element for opening or closing the air connection. The actuator includes a detection unit to detect the arrival at and departure from an end position of the shut-off element when the actuator is activated. The actuator includes a control device which is configured such that, when the actuator is activated, the control device detects the current cycle time between a departure from and the next arrival at the end position by the shut-off element.
