Abstract
A hydraulic actuating assembly for valves for controlling process fluid flows includes a valve that is operated by an actuator and that is pre-tensioned in the direction of a closing position. The actuator has a pressure chamber which is active in the opening direction and which can be connected to a low pressure by means of three parallel relief paths. A secondary relief path, which can be activated in a test mode, is provided.
