What is Trim?
Valve's trim is a collective name for the replaceable parts, in a valve. A typically Trim design includes a disk, seat, stem, and sleeves needed to guide the stem.
A valve's performance is determined by the disk and seat interface and the relation of the disk position to the seat. Because of the trim, basic motions and flow control are possible. In rotational motion trim designs, the disk slides closely past the seat to produce a change in flow opening. In linear motion trim designs, the disk lifts perpendicularly away from the seat so that an annular orifice appears.
