Abstract
A valve assembly includes a first sleeve defining a piston bore therein. A second sleeve defines a piston bore therein. The piston bore of the first sleeve and the piston bore of the second sleeve are axially aligned. A piston is slidingly engaged in the piston bores of the first and second sleeves. A seal carrier with a plurality of pieces is axially between the first sleeve and the second sleeve. The plurality of pieces of the multi-piece seal carrier are circumferentially spaced apart from one another.
