Dosing Valves from Dual Valves Australasia

Dual Valves Australasia introduces a new line of self flushing inline 3-way dosing valves to eDart’s extensive range of slurry-related products.  

The dosing valves are used to neutralise tailings or to control the pH of the medium.  

Typically, rock lime (alkaline) in a ring main is continuously pumped around the circuit because it tends to settle and separate. Normally a T piece is inserted into the line and the flow is controlled with a standard valve (knife or butterfly).  

When the valve is closed the line is filled up with the stagnant lime and blocks. Being located directly in the ring main, the dosing valves eliminate the formation of these blocks.  

As the valve opens the vertical take off line fills up and when closed, the line gravity flushes withoutleaving a pocket of pipe that can solidify.  

The self flushing dosing valves are available in various materials to suit specific process requirements. Sizes also vary and can be customised to the specific application.
