Flanged Ball Check Valves
A flanged ball check valve works with a ball that rolls into a side pocket with the flow and returns to its seat when flow stops. With no hinge, spring or stem it works without clogging in water containing fibres, sand and solids.
It is used in wastewater lift stations, at submersible pump outlets and on sludge and drainage lines. Body and ball materials and pressure class are selected by model and medium.
Main Applications
- Wastewater lift stations
- Submersible pump discharge lines
- Sludge and drainage lines
- Stormwater pump outlets
- Industrial wastewater lines

Which material? In a ball check valve the ball may not fully open when flow velocity is low; when selecting, check the size suited to the pump flow and the minimum velocity in the datasheet.
