 Pressure vs. Temperature |
Electrically actuated 3-way ball valves are useful for redirecting or to stop the flow of liquids in piping systems. These models are designed for aggressive liquids; In standard versions they allow a manual operating for maintenance (or emergency operations) and a position pointer. The power supply must be switched off before a manual operating.
All operating modes (according bore shapes) are described in the data-sheet da913-20.
