Abstract
An actuating unit for a process valve is described, which comprises a pilot valve unit, a separate removable seal arranged between two parts through which a fluid can flow, and a piston configured for the adjustment of the process valve. The seal has through openings for the passage of fluid, and the adjacent parts have holes, such that different holes are in fluid communication with each other via the through openings or are fluidically separated due to an intermediate wall portion of the seal depending on the fitting position of the seal. A process valve having such an actuating unit is furthermore described.
