Electrically actuated 3-way ball valves allow multiple possibilities for controlling the direction of fluid in piping systems. These valves are suitable for applications with aggressive media and are equipped with a manual emergency override and a visual position indicator. The power supply must be switched off when using the manual override.
The different operating modes (L-port or T-port) are described in data sheet da913-20.
