Abstract
A valve seat apparatus for use with fluid valves is described herein. An example valve seat apparatus includes a seat ring having a central passage therethrough and an outer wall. The outer wall comprises a threaded portion, having a first diameter, to engage a cage of a fluid valve. The outer wall also includes a sealing portion to capture a seal assembly between the sealing portion and a surface of a body of the fluid valve. The sealing portion has a second diameter greater than the first diameter. The outer wall of the example valve seat apparatus further includes a flange portion to capture the seal assembly between the cage and the flange portion. The flange portion extends toward the surface of the body and the sealing portion is to be positioned between the flange portion and the threaded portion. The flange portion has a third diameter greater than the second diameter.
