Single eDart valves from Dual Valves Australasia

The external single eDart valves, available from Dual Valves Australasia are ideal for plant retrofits and flotation level control applications. The valve’s flexible orientation makes it suitable for plant retrofits.

Optimised for fine control of slurry flow from one flotation machine to the next, the single eDart valve has a customisable body and flange orientations to suit any plant.

While the plug and seat of the valve are made from polyurethane or any appropriate wear-resistant material, the patented bellows seal has a non-sliding sealing arrangement. The body has a rubber-lined mild steel construction.
