Information About B249+ARX24-MFT
The B249+ARX24-MFT is part of Belimo’s characterized control valve portfolio engineered to deliver stable and energy-efficient hydronic control. The valve body is manufactured from durable materials to support high pressure operation and zero leakage performance in demanding heating and cooling systems. Its integrated ARX24-MFT actuator uses Belimo’s multi-functional technology to allow flexible configuration of control signals, operating ranges, and response behavior. Factory assembly of the valve and actuator ensures reliable performance, simplified installation, and consistent control accuracy in commercial HVAC applications.
Key Features
- Two Way Characterized Valve Design: Provides precise modulating flow control with an equal percentage characteristic for stable hydronic performance.
- MFT Programmable Actuator: Supports configurable control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for broad system compatibility.
- Non Fail-Safe Operation: Powered positioning without spring return supports applications where fail-safe action is not required.
- High Cv Flow Capacity: Cv 46 rating allows efficient flow regulation for medium to large hydronic circuits.
- Electronic Overload Protection: Protects the actuator throughout the full rotation range to prevent mechanical damage and ensure long service life.
- Integrated Position Feedback: Supplies a 2…10 V feedback signal for continuous valve position monitoring and closed-loop control.
- Durable Valve Construction: Designed for chilled and hot water systems with glycol concentrations up to 60 percent and high pressure ratings.
The B249+ARX24-MFT delivers the reliability and precision required for accurate hydronic flow modulation in modern HVAC control systems.
