Abstract
A pneumatic valve, includes an air chamber, a connector for supplying compressed air to the air chamber and one or more connectors for discharging compressed air from the air chamber. The valve includes an actuator with a mobile closure element which, when the actuator is activated, blocks the supply of compressed air via the supply connector, and when the actuator is deactivated, is arranged to permit the supply of compressed air via the supply connector. The actuator is configured such that the closure element, on deactivation of the actuator, is moved by a restoring force into the free position. A check valve with a spring is arranged at the supply connector. The elastic force of the spring in the free position of the closure element prevents back-flow of compressed air from the air chamber into the supply connector when there is no supply of compressed air at the supply connector.
