Information About AFRB24
The AFRB24 is part of Belimo’s spring return actuator lineup developed for dependable valve actuation in HVAC systems. It uses a mechanical spring return mechanism to automatically drive the valve to a predefined safety position during power loss. The actuator supports simple on/off control and allows reversible mounting for both motor and fail-safe direction, providing installation flexibility. Designed for maintenance-free operation, it includes electronic overload protection and robust enclosure construction for long-term reliability.
Key Features
- Spring Return Fail-Safe Operation: Integrated spring mechanism automatically moves the valve to a safety position when power is lost, supporting system protection.
- On Off Control Functionality: Designed for straightforward open and close valve operation in hydronic control systems.
- Reversible Direction Of Motion: Motor and fail-safe rotation direction can be configured through CW or CCW mounting for flexible installation.
- Reliable 24 Volt Power Operation: Operates on standard AC/DC 24 V control power commonly used in HVAC systems.
- Manual Override Capability: Supplied 5 mm hex crank allows temporary manual valve positioning during commissioning or service.
- Electronic Overload Protection: Protects the actuator throughout the full 0…95° rotation range to prevent damage under abnormal conditions.
- Plenum Rated Construction: UL 2043 compliant design supports installation in air plenums per NEC and IMC requirements.
The AFRB24 delivers the reliability and precision required for safe, dependable on/off valve control in commercial HVAC applications.
