The Caleffi 145013 is an electronic proportional linear actuator: 24 VAC/VDC electronic proportional linear actuator with 0(2) to 10 V control signal and 0 to 10 V position feedback. It modulates valve position from a control signal rather than switching open and closed.
Best for modulating control where a proportional signal drives valve position.

Key Features
Proportional Electronic Actuation
A motor-driven linear actuator positioned by a control signal: 24 VAC/VDC electronic proportional linear actuator with 0(2) to 10 V control signal and 0 to 10 V position feedback. It modulates valve position rather than switching fully open or closed.
Position Feedback
A feedback signal reports actual stem position back to the controller, so the control loop can verify the commanded position was reached.
Fail-in-Place Operation
On loss of control signal or power the actuator holds its last position rather than driving to a preset end position. It does not provide a spring or capacitor return.

Frequently Asked Questions
What does Caleffi 145013 do?
It is an electronic proportional linear actuator: 24 VAC/VDC electronic proportional linear actuator with 0(2) to 10 V control signal and 0 to 10 V position feedback. It modulates the valve rather than simply opening or closing it.
Is Caleffi 145013 a thermo-electric actuator?
No. A thermo-electric actuator uses a heated wax element and switches between open and closed. This is a motor-driven electronic actuator that positions the valve proportionally from a control signal and reports position back.
What is the warranty on Caleffi 145013?
Caleffi covers this product under its standard two-year limited warranty against defects in material and workmanship from the date of shipment. ZOT Supply is an authorized Caleffi distributor.
