Model 3700 Cast Iron Flanged Ball Valve

American Valve’s 3700 Series™ provides the best alternative to gate valves, exactly matching their end-to-end and flanged dimensions. Unlike gate, plug, and butterfly valves, 3700 Series™ valves are designed to maintain a bubble-tight shut off that exceeds ANSI Class VI for many years, even if the valve has not been operated or maintained regularly. The 3700 Series™ valves are certified to meet the requirements of NSF/ANSI 61 and NSF/ANSI 372 for drinking water. All 3700 Series™ valves are rated at 200 psig @ 200º F, and are full port in all sizes. Ideally suited for potable water, wastewater, or other liquids and compressed air. 3700 Series™ valves are bi-directional; flow may go in either direction. They may be mounted horizontally, vertically, or at an angle and can be locked in either the open or closed position. 2” square operating nuts are available for underground service or hard-to-reach installations.
