Abstract
Rotary valves and related valve trims. A valve trim for a rotary valve assembly includes a valve shaft, a flow control element coupled to the valve shaft, and a coupling assembly for coupling the valve shaft to the flow control element. The coupling assembly includes an expansion pin having a central bore and a taper pin sized for insertion in a central bore of the expansion pin. The expansion pin and the taper pin together are sized for insertion into a cross bore of the flow control element and through a lateral bore of the valve shaft. A retainer is arranged to maintain the taper pin in the central bore of the expansion pin. The retainer limits movement of the taper pin relative to the expansion pin.
