Unique universal power supply models work with 24 Volt AC to 240 Volt AC or 24 Volt DC to 125 Volt DC. The new EFB Series is true spring return with a high 270 in-lb torque output and most models are available with optional NEMA 4 housing. It is possible to dual-mount EF actuators on one shaft, for a total of 540 in-lb.

Fail-safe actuators control connected dampers while ensuring they function safely in an emergency. They use a motor to move the connected damper and feature a spring-return mechanism to move them to a safe position in the event of a power loss.

The LF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.

anti-rotation device to prevent the actuator from rotating. Adjustable angle of rotation with mechanical end stops. the end stop is reached.

The LF24-SR-S-20 is used for proportional modulation of dampers and control valves in HVAC systems. The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500W resistor, a 4 to 20 mA control input from an electronic controller or positioner.
