Control Ball Valve features a characterized ball design that creates a gradual change in flow rather than the sudden change typical with traditional ball valve styles. Characterized Control Ball is available as an option on the Type 546 valve and features all plastic construction and excellent flow characteristics. This makes it ideal for aggressive media in a wide variety of applications. Ball valve offers full flow and low pressure loss in the open position. Control angles range from 0-90° for maximum flexibility. Available in ½” to 2” sizes, material choices include PVC, CPVC, PP and PVDF with options for manual or actuated versions.
