Abstract
A travel stop assembly is provided for a valve and an actuator. The travel stop assembly includes a coupling which can be non-rotatably engaged between the valve stem and the actuator shaft to transmit rotation from the actuator shaft to the valve stem. The coupling includes a flange intermediate its length with a pair of opposed stop surfaces thereon. A pair of threadedly adjustable bolts are mounted intermediate the valve and the actuator for threaded advancement toward or away from the coupling. The bolts are angularly aligned to one another and can be independently advanced or retracted to engage the stop surfaces of the flange on the coupling to control the maximum rotation of the coupling and hence the valve stem.
