Abstract:
Valve stem and valve plug apparatus for use with fluid regulators are described herein. An example fluid regulator includes a flow control member having a body that includes a longitudinal bore between a first end and a second end and a valve stem is disposed in the bore of the flow control member. A connector slidably couples the valve stem and the flow control member such that the connector moves away from the flow control member to relieve the flow control member of a loading force imparted by a loading element of the fluid regulator when the flow control member sealingly engages a valve seat of the fluid regulator.
