Key Features

Proportional Electronic Actuation

A motor-driven linear actuator positioned by a control signal: 24 VAC/VDC electronic linear actuator with proportional or two-point control and fail-safe function. 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.

Selectable Fail-Safe

Fail-safe behavior is selectable, determining whether the valve drives closed or open on loss of control signal or power.
