When the actuator is driven by a 3-position or DC 0...10 V control signal, it generates a
stroke which is transmitted to the valve stem.
•
Voltage at Y1:
•
Voltage at Y2:
•
No voltage at Y1 or Y2:
•
The valve opens / closes in proportion to the control signal at Y
•
At DC 0 V, the valve is fully closed (A → AB)
• In the event of a power failure, the actuator maintains its current position
