Description

Product Description

The BELIMO EFX24-SR-S N4H is a direct coupled actuator with 270 in-lb torque. It is designed for fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. It provides a feedback signal for position indication or master-slave applications.

  • Provides constant torque to the damper with, and without, power applied to the actuator
  • May be stalled anywhere in its normal rotation without the need of mechanical end switches
  • Provided with two built in auxiliary switches that provide safety interfacing or signaling

Product Highlights

This actuator offers reliable damper control with spring return functionality and versatile control options.
