Abstract (en)
[origin: WO0001968A1] A device for actuation of a valve member released automatically from a first position of readiness for safety shut-off or safety opening of a flow upon occurrence of a need thereof comprises an arrangement (29-37) adapted to cause a movement of a valve body of the valve member in the position of readiness into a second position of an opposite type, open or shut-off, upon occurrence of the need and a member (21) controlled by hand power and substantially rigidly connected to the valve body through a transmission means, so that the position of this member directly corresponds to a determined position of the valve body. The control member is adapted to bring the valve body from the second position obtained after said release through movement thereof by hand power into a first position for resetting the device to the position of readiness.
