Flanged PVC-U Ball Valves
A flanged PVC-U ball valve is a shut-off valve with an unplasticised rigid PVC body, bolted into the line by flanges at both ends, that opens and closes in a quarter turn.
It is used as a large isolation valve on chemical process, acid-alkali neutralisation, reverse osmosis and wastewater treatment lines. Size, seal and flange standard are selected according to the fluid and model.
Main Applications
- Acid-alkali neutralisation lines
- Reverse osmosis and demineralisation plants
- Chemical lines in wastewater treatment
- Chemical storage tank outlets
- Galvanising and surface treatment plants
- Pool disinfection lines
