Abstract
A valve drive is indicated, having a housing, a spindle for displacement between an open position and a closed position and is coupled at one end to a valve closing member, and a return spring which urges the spindle to the closed position or to the open position. The housing has an opening in an area through which the centerline of the spindle extends, and the valve drive includes a closure member to close the opening. The housing and the closure member are configured such that the closure member can be fastened to the housing in an operating position and in a cleaning position to cover the opening. The closure member has a recess on a face side that is on the inside in the operating position, allowing the spindle to move unhindered therein during operation of the valve, and has a fastening structure on the opposite, outside face side. In the cleaning position, the closure member is turned over as compared to the operating position, wherein the fastening structure in the cleaning position allows the spindle to be fastened to the closure member in a form-fitting and/or force-fitting. Furthermore, a method of cleaning a valve is indicated.
