The Pratt Ballcentric® Plug Valve available in sizes ranging from 1/2" – 72" is designed specifically for wastewater applications. The round port design available on sizes 1/2" – 12", offers the least resistance to slurry, sludge, and fluid flow resulting in less erosion, longer service life, and reduced pumping costs. The large round port design can pass larger solids reducing plugging problems. Round port valves offer the best flow characteristics compared to alternative port openings, resulting in less pressure drop across the valve. Pressure classes on 12" and smaller is 175 psi, pressure classes on 14" and larger is 150 psi, higher pressure on request.
