Abstract:
1. A valve closure system for operating a valve of a fluid-containing vessel between an open and a closed position to allow and disallow communication of the interior of the vessel through the valve, the valve closure system comprising: an operating part shaped to engage and rotate a rotary actuator protruding along an axis from a valve body to operate the valve from one position to another when the valve closure system is associated with the valve; a motor for rotating the operating part about the axis; a walled located part disposed on a housing of the motor; and a walled locating part shaped for mounting on the valve body, the walled parts respectively comprising respective walls shaped to mutually telescopically engage in a direction parallel to the axis when, with the walled locating part mounted on the valve body, the motor housing has been properly circumferentially and axially aligned with the locating part along the axis and then advanced axially to move the operating part toward engagement with the rotary actuator of the valve, the wall of the walled locating part being spaced from the valve body when the walled locating part is mounted on the valve body and having opposite faces that respectively face toward and away from the valve body, and the wall of the walled located part comprising opposite faces that respectively face toward and away from the valve body, one of which is disposed in confronting relation to one of the faces of the wall of the walled locating part when the walls are in mutual telescopic engagement.
