Belimo AF24 Spring Return Actuator

Fail-safe rotary actuator with spring return for valve or damper positioning

Overview

This is a Belimo AF24 Spring Return Actuator, designed to provide reliable, fail-safe rotary actuation for valves and dampers in HVAC and industrial control applications. Operating on AC 24V or DC 24V, it delivers dependable motor-driven positioning with spring return for safe fail-position behavior on power loss.

Key Features

  • Fail-safe spring return: Ensures safe positioning on power loss, with a minimum spring return torque of 15 Nm.
  • Adequate motor torque: Minimum 15 Nm at rated voltage.
  • Adjustable rotation angle: Max. 95°, adjustable from 33% in 5.5% steps with a supplied limit stop.
  • Optional auxiliary switch: AF...-S variant includes 2 x SPDT 6(3)A, AC 250V switches with fixed 5% and adjustable 28-94% switching points.
  • Selectable rotation direction: Set by L/R mounting.
  • Long service life: Approx. 60,000 operations.
  • Mechanical position indicator: Visual feedback of actuator position.
  • Robust protection: IP54 degree of protection, safety extra-low voltage class.
  • Wide ambient temperature range: -30°C to +50°C.
