Define which of the two circuits should remain active in the event of a failure — for example, in a production diversion system with an L-port, define whether in case of failure the flow should go to the safety tank or continue to the process. This decision determines the actuator configuration (NC or NO) and the mounting position.\n  \u003c\/li\u003e\n\n  \u003cli\u003e\n\n    \u003cstrong\u003eDo not use in intermediate position for regulation:\u003c\/strong\u003e The 3-way ball valve is an ON\/OFF component — it operates between its two extreme positions (0° and 90°).
