Abstract

The drive has with an operating element (21) e.g. piston, which is movably supported in an operating cylinder (20), where the operating element is provided for driving a valve (22). A fluid conduit is provided on a side of the operating element in the operating cylinder. Non-return valves (30, 31) for controlling the fluid flow are connected in series or in parallel to an actively operable control valve (29). The operating element is hydraulically and/or pneumatically operated.
