The Series 2100 Suction Demand Valve (SDV) is designed for the dosing industry to hydraulically isolate a metering pump from its bulk supply tank. This isolation prevents variations in suction pressure caused by changes in tank liquid levels, supporting consistent pump accuracy.

By maintaining dosing accuracy, the valve reduces wastage of primary injected chemicals and minimises the need for subsequent neutralising chemicals.

The Series 2100 SDV also acts as a safety device, preventing uncontrolled discharge from the storage tank in the event of a downstream pipeline rupture, reducing risks to personnel and the environment.
