Anti-rotation assemblies for use with fluid valves

摘要

Anti-rotational assemblies for use with fluid valves are disclosed herein. An example anti-rotation assembly includes an anti-rotation retainer to couple to a flow control member of a valve and an anti-rotator to engage the anti-rotation retainer. The anti-rotator prevents rotation of the anti-rotation retainer relative to a longitudinal axis of the anti-rotation retainer when the anti-rotation retainer is disposed in the valve.
