    external dart valve - edart group

    The Dual eDart is an external dart valve mounted on the side of a flotation cell. It has been optimised for variable slurry flow by having two plugs and seats within the body. This gives the valve a high rangeability and fine control. Because the valve is external to the vessel it is well suited to upgrade projects and where safety is a concern. The valve, in conjunction with knife gate valves, may be isolated and easily …
