Belimo B277+AFRX24-MFT-S
The Belimo B277+AFRX24-MFT-S is a high-performance 3-inch NPT 2-way characterised control valve and actuator assembly designed for demanding hydronic applications. This stainless steel ball valve features a 70 Cv rating and utilizes a specialized A-type characterized disc to ensure a true equal percentage flow characteristic, preventing hunting in the control loop. Driven by the AFRX24-MFT-S spring return actuator, this assembly provides 180 in-lb of torque and proportional control via a 2-10VDC signal, though it is field-configurable via Multi-Function Technology (MFT) for various input styles. The rugged NEMA 2 enclosure and built-in auxiliary switches facilitate seamless integration into complex building automation systems. Built to handle chilled or hot water and up to 60% glycol solutions, this heavy-duty HVAC actuator and valve combination ensures reliable fail-safe operation in critical mechanical rooms where precise flow regulation is non-negotiable.
- Corrosion Resistance: Features a 304 stainless steel ball and stem for longevity in diverse water chemistries.
- Zero Leakage: Rated for bubble-tight shut-off (ANSI Class VI), reducing energy waste in bypass circuits.
- MFT Programming: Allows for custom parameter settings including control signal, feedback, and running time.
- Integrated Feedback: Dual SPDT auxiliary switches provide positive verification of end-positioning for sequencing.
- High Close-off Pressure: Designed to maintain tight control even under high differential pressure conditions.
Common Questions
What is the fail-safe position of the AFRX24-MFT-S?
This is a spring-return assembly; the actuator can be mounted to fail either normally open or normally closed depending on the application requirements.
Can the control signal be changed from 2-10VDC to 4-20mA?
Yes, through the Multi-Function Technology (MFT) interface, the input signal can be reconfigured to 4-20mA using a 500? resistor or via the Belimo PC-Tool.
What is the maximum fluid temperature rating?
The B277 valve body and trim are rated for a fluid temperature range of 0°F to 250°F (-18°C to 120°C).
