A method for operating a hydraulic pressing device, for example, a pipe clamping device, that includes a stationary part and a moving part. The hydraulic pressing device also includes an automatically actuating return valve. The moving part of the hydraulic pressing device is displaced relative to the stationary part until a predetermined pressure is reached. At that point, the moving part returns automatically and completely back into its initial position, which is released as a result of the predetermined pressure being reached. The moving part is biased into its initial position by means of a return spring and, on removal of the restoring force, returns automatically back into its initial, closed condition.
