A fail-safe motorized ball valve is an electrically actuated valve designed to automatically move to a predetermined safe position when electrical power is lost.
Unlike a standard motorized ball valve that may remain in its last position after a power failure, a fail-safe valve automatically returns to a defined position—typically fully open or fully closed, depending on the system requirements.
This feature makes fail-safe motorized ball valves particularly useful in applications where an unexpected power outage could cause water leakage, equipment damage, process interruption, or other operational risks.
