Abstract
Shaft retaining assemblies for use with fluid valves are described. In a described example, a bonnet assembly for use with a fluid valve includes a bonnet defining a passage to receive at least a portion of a shaft of the fluid valve. The bonnet is to be removably coupled to the fluid valve. Additionally, the example bonnet assembly includes a retaining assembly mounted in the bonnet to be substantially not exposed to a flow of fluid through the fluid valve. The retaining assembly is to control an amount of movement of the shaft along a longitudinal axis of the shaft to enable an alignment of a sealing element coupled to an end of the shaft relative to a seating surface of the fluid valve.
