The actuator, specifically designed for 90° operation(e.g., ball valves,butterfly valves). The failsafe function by means of a Supercap Capacitator ensures OPEN or CLOSED position on power loss.The supercap is charged via the actuator power supply in operational mode.
FAIL-SAFE
The failsafe is purely an emergency function and serves no other purpose.
Actuator is operated electricallyin normaluse
CHARGING
