VALVE OPERATING DEVICE HAVING A MOVABLE ARM FOR USE IN EXERCISING VALVES

Abstract:

A valve operating device includes first and second pivots, a first arm portion extending therebetween, a second arm portion extending from the second pivot, a valve operating machine on the second arm portion, and an actuator connected between the first pivot and the first arm portion. The first arm portion can rotate around a first vertical axis defined by the first pivot and can pivot around a horizontal axis defined by the first pivot. The second arm portion can rotate around a second vertical axis defined by the second pivot. The actuator causes the first and second arm portions, the second pivot, and the valve operating machine to pivot upward and downward relative to the first pivot around the horizontal axis.
