Abstract: A gate nut connects the gate element to a valve stem and spring mounted plungers on the gate element position and retain the gate nut in position on the gate element. When employed with a gate assembly of the expanding type having a gate element and segment, the nut contacts the segment of the gate assembly to limit the expansion of the gate assembly to prevent binding the gate element and segment against the seats.
