Series ABO 200 knife gate valves are a unidirectional wafer type valve ideal for installations handling liquids that contain suspended solids and waste water. These valves are especially useful in facilities with limited space, thanks to their small size and light weight. A circular blade bevel prevents excessive wear and clogging, ensuring long-life service. Reinforced with oversize top and bottom ends to ensure proper sealing, these valves can be manufactured with bonnets to provide total water tightness.
