Information About B280+ARB24-3
The B280+ARB24-3 is part of Belimo’s characterized control valve range developed to provide stable and repeatable flow control in medium to large hydronic circuits. The valve uses a full-flow stainless steel ball and equal percentage control characteristic to maintain consistent regulation across varying load conditions. Its factory-mounted ARB24-3 actuator supports floating point control and non fail-safe operation, ensuring reliable positioning during normal system operation. Built for maintenance-free service, this assembly integrates durable materials with precise actuator control for long-term HVAC performance.
Key Features
- High Capacity Two Way Valve Design: Cv 170 rating supports effective control of large water volumes in distribution piping.
- Equal Percentage Flow Characteristic: Provides smooth and predictable modulation across the valve’s operating range.
- Non Spring Return Floating Actuator: Supports floating point and on/off control while maintaining last position on power loss.
- Compact Brass Valve Construction: Nickel-plated brass body with stainless steel trim ensures corrosion resistance and durability.
- Low Power Consumption: Efficient 24 V actuator design minimizes electrical load on control transformers.
- Service-Friendly Operation: Manual override and mechanical position indication simplify commissioning and maintenance tasks.
- Proven HVAC Compatibility: Rated for chilled and hot water systems with glycol mixtures up to 60%.
The B280+ARB24-3 delivers the reliability and precision required for accurate hydronic flow control in commercial HVAC applications.
