摘要： Collets for coupling rotary actuators to valves are disclosed. An example collet includes a first plurality of flexible members configured to be coupled to an elongated member and each having a first inner surface and a first outer surface. The first inner surface and the first outer surface define a first cross-sectional shape. The example collet further includes a second plurality of flexible members configured to be coupled to the elongated member and each having a second inner surface and a second outer surface. The second inner surface and the second outer surface define a second cross-sectional shape that is different from the first cross-sectional shape of the first plurality of flexible members. The first and the second outer surfaces are to engage a third inner surface of an opening of a lever that is configured to cause the first and the second plurality of flexible members to be displaced toward an axis of the elongated member to cause the first and the second inner surfaces to engage one or more surfaces of the rectangular shaft.

摘要： Apparatus to bias valve closure members are described. An example valve includes a valve body having an opening defining a passageway. The opening has an axis that is substantially coaxially aligned with a flow path axis defined by the passageway. A first shaft supports a closure member within the passageway of the valve body and relative to the opening and an end cap removably coupled to the valve body retains the shaft within a bore of the valve body. A spring is disposed between the first seating surface and a second seating surface opposite the first seating surface to provide a force to oppose the weight of the closure member and facilitate alignment of the closure member relative to the opening of the passageway.
