摘要：
A valve assembly includes a first sleeve (102) defining a piston bore (104) therein. A second sleeve (106) defines a piston bore (108) therein. The piston bore of the first sleeve and the piston bore of the second sleeve are axially aligned. A piston (110) is slidingly engaged in the piston bores of the first and second sleeves. A seal carrier (112) 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.
