Three-way ball valve is isolating valve designed to redirect
the service fluid flow. It is not designed to be used for throttling or
regulating purposes. For temperatures from −50 °C to +200 °C.
Suitable for water, steam, gas, oil, crude oil, acid, alkali and other
liquids and gases without mechanical impurities.

- DN 10 – DN 150, PN 16 – PN 250
- NPS ½″ – NPS 6″, Class 150 – Class 1500
- floating ball,
- full bore,
- anti-static design,
- stem secured against release (anti-blow-out),
- ball bore form of either “L” or “T”,
- flow direction unlimited,
