Abstract
A valve has a closure member for closing a valve orifice, particularly so as to be tight against gas, in a closed position of the closure member. The closure member can be moved in a closing process by at least one actuator starting from a first position of maximum opening at least along a first partial distance with a linear movement component in direction of its closed position, and the actuator carries out a closing stroke with a linear stroke direction for a movement of the closure member with this movement component. The actuator is so arranged in relation to the closure member that an angle diverging from 0° and 180° is provided between the linear movement component of the closure member along the first partial distance, proceeding from the first position of maximum opening, and the linear stroke direction of the actuator.
