Abstract: Balanced plug assemblies and pressure regulators having balanced plug assemblies are described herein. A pressure regulator disclosed herein includes a device body defining a fluid passageway between an inlet and an outlet. The device body defines a channel between the fluid passageway and a pressure sense chamber. The pressure regulator includes a seat in the fluid passageway, a stem having a flange, and a plug coupled to the stem. The pressure regulator also includes a stem guide disposed in the channel of the device body. The flange of the stem disposed in a balance chamber of the stem guide and divides the balance chamber into a first balance chamber portion and a second balance chamber portion. The stem guide at least partially forms a balance passage that fluidly couples the pressure sense chamber and the second balance chamber portion.

Abstract: Fluid valve bodies and improved methods of manufacture are disclosed. A disclosed fluid valve body includes a pipe and a second member coupled together to form at least a portion of the valve body.

Abstract: A vibration damper apparatus for use with fluid control devices is disclosed. An example fluid control device includes a housing and a piston having an outer circumferential surface and configured to be responsive to pressure within the housing to control the position of a fluid flow control member within the housing. The example fluid control device also includes a guide ring coupled to the housing and having an opening configured to receive at least a portion of the piston, and a vibration damper disposed between the guide ring and the piston to frictionally engage the outer circumferential surface of the piston.
