Abstract
An insert adapted for use in a plug valve includes a single-piece body having an inner sidewall adapted to interface with a sidewall of a valve plug. First and second opposing apertures are each defined through the single-piece body for selective alignment with a flow bore of the valve plug. First and second opposing slots are each defined through the single-piece body at an angle to the first and second opposing apertures for allowing the body to flex in the direction of the first and second opposing apertures.
