Common questions on this part
Yes. When ordered with the modulating control option, the actuator includes an internal electronic servo card that accepts a 4–20 mA DC control command and outputs a 4–20 mA position feedback signal to your PLC, SCADA, or BMS system.
The electric actuator is non-backdriving (self-locking worm drive), so the valve maintains its exact current position upon power loss. A declutchable manual handwheel allows operators to open or close the valve manually until power is restored.
