A seal assembly (202) for use with valves having a two-piece cage is described. An example seal assembly includes a body defining a bore extending along an axis to slidably receive a closure member. The body includes a first portion (216) removably coupled to a second portion(218). The first portion includes a first groove (236) and the second portion includes a second groove (240). The first and second grooves form a sealing surface (242) when the first portion couples to the second portion. The example seal assembly further includes at least one sealing member (250) disposed adjacent the sealing surface to provide a seal against the closure member and a biasing element (254) to bias the sealing member toward the sealing surface. |
