Description

Product Description

The BELIMO NFB24-SR-X1 is a direct coupled actuator with a spring return, designed for modulating control with 24 VAC/DC power. It accepts a 2 to 10 VDC or 4 to 20 mA control signal. This actuator provides reliable fail-safe operation and positive close-off on airtight dampers. It delivers constant torque to the damper, whether power is applied or not.

  • Provides true spring return operation for reliable failsafe application
  • 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

Product Highlights

The NFB24-SR-X1 actuator is ideal for valve and damper applications, offering modulating control and fail-safe functionality.
