What is proposed is a valve arrangement for actuating sliding doors, in which the valves (28, 32) and throttles (56) necessary for opening and closing and for locking and unlocking the doors are arranged in a solid block (50) and are connected by way of channels (36, 38, 54, 58, 60) present in the latter. The insertion of throttles and follow-up valves (28, 32) into the connections between pilot valves and pneumatic cylinders for opening and closing the sliding doors ensures that the opening of the doors can take place only after the unlocking of these and locking can take place only after the complete closing of the doors. <IMAGE> |
