Selection of control valves on water optimisation projects

Controlling water flow to underground mining sections reduces the amount of water required to be pumped back to surface. This results in significant energy savings. Water flow and pressure can be controlled by installing control valves at strategic positions throughout the water reticulation system. Valve selection/specification requires several constraints to be satisfied in order to ensure an effective solution. The process of analysing system parameters to determine characteristics is discussed. Possible solutions are evaluated to select a suitable valve solution based on the determined constraints.
