In the case of a valve, having a valve housing (12) through which process medium is able to flow and in which a valve seat (17) surrounding a through-flow opening (16) is arranged, a valve member (18) arranged on a spindle (19) being assigned to said valve seat (17) such that the valve member (18) is movable by means of an adjusting travel of the spindle (19) between a shut-off position, in which the valve member (18) bears in a sealing manner against the valve seat (17) so as to be impermeable to process medium, and an open position, in which the valve member (18) is lifted from the valve seat (17), and having a valve drive (28) which has a drive housing (29) and a drive member that is arranged in the drive housing (29) and generates the adjusting travel of the spindle (19), wherein the drive housing (29) is coupled or couplable to the valve housing (12) via an external interface (49) and the drive member is coupled or couplable to the spindle (19) via an internal interface (50), the external interface (49) is assigned first actuating means and the internal interface (50) is assigned second actuating means such that the actuation of the first actuating means in order to couple or uncouple the drive housing (29) and valve housing (12) causes actuation of the second actuating means in order to couple or uncouple the drive member and spindle (19).
