Threaded Ball Check Valves
A threaded ball check valve works with a ball that slides into a side pocket when flow starts and returns to its seat when flow stops. With no hinge or spring it runs without clogging in water with solids and fibres.
PVC-U models in PN16 class serve small lines with chemical and corrosive water; cast-bodied models are used for drainage and submersible pump outlets. Size and ball material are selected by model.
Main Applications
- Drainage and sump pump outlets
- Small submersible pump lines
- Chemical dosing lines (PVC-U)
- Small rainwater and wastewater lines
- Pool and treatment circuits
