FLUID FLOW CONTROL MEMBERS FOR USE WITH VALVES

摘要

Fluid flow control members for use with valves are de-scribed herein. An example fluid flow control member for use with a valve includes a body having a first seating surface to control a flow of fluid through the valve. The body defines a second seating surface opposite the first seating surface to control a flow of fluid through the valve. Addition-ally, the body defines an aperture to receive a stem of the valve, and a bore surrounded by the first seating surface to receive at least one of a seal or a sliding member each of which have a first surface to be engaged by a sec-ond surface of a spring seat coupled to the stem to control a fluid flow through the valve.
