Cam-Centric plug valves from Val-Matic Valve & Manufacturing Corp. can handle slurries, grit or solids. Features include a heavy-duty fully rubber encapsulated plug, welded nickel seat, grit seals and V-Type packing. QuadroSphere trunnion mounted ball valves allow particulates for media such as liquids, gases and slurries to flow above, below and around the sides of the ball. Recessed surfaces on the ball provide lipped edges that wipe the seat surfaces clean during opening and closing, preventing clogging by avoiding high scale and solids buildup. 630/941-7600; www.valmatic.com.
