Belimo afrx24 Spring Return Valve Actuator 24V 180 In-lb

Product Description

The BELIMO afrx24 is a spring return valve actuator designed for direct-mount installation on commercial and industrial valve assemblies. It operates on 24 volts AC or DC and delivers 180 inch-pounds of torque, making it suitable for driving ball valves and butterfly valves in HVAC hydronic and air-handling systems. The actuator uses an on/off control signal and features a run time of under 75 seconds with a 20-second spring return for fail-safe positioning. Licensed HVAC and mechanical contractors install this type of actuator as part of building automation and temperature control systems.

The afrx24 is intended for use in commercial HVAC applications where reliable fail-safe valve control is required. Typical installations include hydronic heating and cooling coil control, chilled water systems, and air handling unit valve service. This actuator is a configurable unit and must be specified before purchase to ensure correct valve pairing and mechanical fit. It is not a shelf-stock replacement and is ordered to configuration.

Key Features

• Spring return fail-safe design with 20-second return time
• 24 volts AC/DC power input for broad control system compatibility
• 180 inch-pounds of torque output for positive valve seating
• On/off control signal type for straightforward integration
• Run time under 75 seconds for responsive valve actuation
• 5-year manufacturer warranty

Compatibility

Designed for direct-mount installation on commercial HVAC valve assemblies. This is a configurable product and must be matched to a compatible valve before purchase. Contact your supplier or BELIMO representative to confirm correct actuator-to-valve pairing for your specific application.

Installation Notes

Installation should be performed by a licensed HVAC or mechanical contractor familiar with building automation control wiring. De-energize the control circuit and isolate the valve assembly before mounting the actuator. Verify that the valve shaft size and direct-mount interface match the actuator configuration prior to installation. Low-voltage wiring should comply with NEC requirements for Class 2 circuits.
