Patent ID: 6840503

Claim:
A valve operating system for turning an actuator of a valve about an axis relative to a body of the valve to operate the valve between first and second positions, in one of which the valve is open and in the other of which the valve is closed, the system comprising: a motor having a rotatable shaft; a bracket for associating the valve operating system with the valve; and an operative coupling for causing rotation of the motor shaft to turn the valve actuator to operate the valve; wherein the bracket is constructed and arranged for fitting onto the valve and comprises a) a ring for coaxially encircling the valve body axially beyond a radially outwardly open groove in the exterior of the valve body, b) locking parts that are disposed axial of the ring and positionable on the bracket for selective engagement with, and disengagement from, the groove to axially lock the bracket to the valve body when engaged with the groove and to axially unlock the bracket from the valve body when disengaged from the groove, and c) additional parts for locking each locking part to the ring when the respective locking part is engaged with the groove and presenting a dimensional interference to the valve body to restrict turning of the bracket on the valve body as the motor operates the valve.
