Abstract
Embodiments of the invention provide a trim arrangement for a ball valve. The trim arrangement can include a first seat assembly having a first seat, a threaded collar, and a biasing element. The first seat can be in contact with a first side of a ball element, and the threaded collar can be threadably coupled to the first seat and can be in engagement with the biasing element. The trim arrangement further includes a second seat assembly having a second seat in contact with a second side of the ball element. The threaded collar can have a profile that is configured to non-rotatably and slidably engage a corresponding profile of a collar bore of the valve body to prevent rotation of the threaded collar relative to the valve body.
