The valve features a durable internal design that supports zero leakage performance and consistent flow characteristics in heating and cooling systems. Its integrated AFRX24-MFT spring return actuator uses Belimo MFT technology, allowing flexible configuration of control signals, operating ranges, and response behavior. Factory assembly ensures proper valve-to-actuator alignment, reducing installation time and supporting long-term reliability in commercial HVAC applications. Key Features Three Way Ball Valve Assembly: Provides accurate changeover or diverting control with a modified linear flow characteristic for stable hydronic performance. Spring Return Fail-Safe Actuator: Automatically drives the valve to a defined safety position during power loss to protect system operation. MFT Programmable Control Technology: Supports configurable control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for broad system compatibility. High Flow Capacity: Cv 57 rating supports efficient control of medium to large hydronic circuits with minimal pressure drop. Zero Leakage Valve Design: Ensures tight shutoff and reliable separation of flow paths during changeover or diverting operation. Integrated Position Feedback: Provides a 2…10 V feedback signal for continuous valve position monitoring and closed-loop control. Manual Override Capability: Supplied hex crank allows manual positioning during commissioning or maintenance activities. The B340L+AFRX24-MFT delivers the reliability and precision required for accurate hydronic flow modulation and dependable fail-safe valve control in HVAC systems.
