摘要： 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).
摘要翻译：在具有工艺介质能够流过其中的阀壳体（12）并且其中布置了围绕通流开口（16）的阀座（17）的阀的情况下，布置阀构件（18）在配属于所述阀座（17）的心轴（19）上，使得所述阀构件（18）能够借助所述心轴（19）的调节行程在关闭位置和关闭位置之间移动，在所述关闭位置，所述阀构件 18）以密封的方式抵靠在阀座（17）上以便对过程介质不可渗透;以及打开位置，其中阀构件（18）从阀座（17）抬起并且具有阀具有驱动壳体（29）和布置在所述驱动壳体（29）中并且产生所述主轴（19）的调节行程的驱动构件的驱动装置（28），其中所述驱动壳体（29）联接或可联接到所述阀壳体（12）经由外部接口（49）并且所述驱动构件经由内部接口（50）联接到或可联接到所述主轴（19），所述外部接口（49）被分配第一致动装置并且内部接口（50）被分配第二致动装置，使得第一致动装置的致动以使驱动壳体（29）和阀壳体（12）联接或分离致动第二致动装置，以便联接或断开驱动构件和心轴（19）。
