Threaded PVC-U Ball Valves
A threaded PVC-U ball valve is a shut-off valve with an unplasticised rigid PVC body and female threaded ends that opens and closes in a quarter turn of the handle.
It is used on process, treatment and dosing lines carrying fluids that attack metal valves, such as acids, alkalis and brine. The product range covers single- and double-female threaded models from 3/4″ (Ø25) to 3″ (Ø90).
Main Applications
- Acid and alkali dosing lines
- Water treatment and reverse osmosis plants
- Galvanising and plating bath lines
- Pool chemical feed
- Brine and seawater lines
- Laboratory and process water

Which material? The body of a PVC-U valve resists many acids and alkalis; the limit is usually set by the seal. The seal material should be chosen after stating the fluid and concentration. Pressure and temperature values are confirmed per model.
