Abstract

A valve device, in particular a lifting valve device, includes a housing, a valve seat, and a movable closing body that can be brought into an open position in an opening movement and into a closed position in a closing movement. In the closed position, the closing body and the valve seat are in sealing contact. The valve device also includes a piston to which a pressure medium can be applied and that is received in a cylinder. To improve hygienic properties, it is proposed that the cylinder is part of the closing body.
