Suction Demand Valves

Suction demand valves

The Series 2100 suction demand valve (SDV) is designed specifically for the dosing industry to hydraulically isolate a metering pump from its bulk supply tank to prevent variations in suction pressure and hence pump accuracy due to rising and falling tank liquid levels.

By improving the dosing pump’s accuracy the valves provide two savings – first, by reducing wastage of the primary injected chemical and then by reducing the required amount of any subsequent neutralising chemicals. The 2100 valve also has a significant added benefit – it will prevent uncontrolled discharge from the storage tank in the event of a pipeline rupture downstream from the valve, thus preventing potential harm to personnel and environmental pollution.
