The QuadroSphere ball valve from Val-Matic Valve & Manufacturing Corp. has a contoured ball with four recessed surfaces that allow solids to be flushed from the body/ball cavity, preventing them from being trapped around the back of the seat rings and bearings. Recessed surfaces on the ball provide lipped edges for scraping the seats clean to avoid buildup of solids and scale. 630/941-7600; www.valmatic.com.
