A pneumatic valve comprises a housing with an air chamber having a supply, connecting opening for connecting the air chamber to an air cushion and a discharge openings. An actuator with a movable closing element is arranged in the housing, featuring a plunger, which projects through the discharge opening with a plate and a first sealing element for closing the discharge opening with an elastic element which, in the activated state, presses said sealing element against the discharge opening The actuator is in the form of an SMA actuator, wherein the actuator element is configured to, in a non-energized state, bring the actuating element to a first state in which it presses the plunger against the supply opening, and to, in an energized state, bring the actuating element to a second state in which the actuating portion does not exert any force on the plunger, wherein a second sealing element is arranged in the air chamber and functions as a check valve.
