Description
The Belimo B320L+LRX24-MFT is a factory-assembled combination of the B320L 3/4-inch 3-way butterfly valve body and the LRX24-MFT non-spring-return rotary actuator, engineered for precise flow control in commercial HVAC hydronic and air-handling applications. The pre-matched valve and actuator pairing eliminates field assembly guesswork and ensures optimal performance right out of the box.
Valve Body — B320L
- Pipe size: 3/4 inch
- Configuration: 3-way (mixing/diverting)
- Flow coefficient (Cv): 12.8
- Design: Butterfly valve for low-pressure-drop, high-flow applications
- Compact, lightweight construction suited for tight mechanical spaces
Actuator — LRX24-MFT
- Supply voltage: 24V AC/DC
- Control type: MFT (Multi-Function Technology) — field-configurable for 0–10V, 2–10V, 0–20mA, or 4–20mA control signals
- Operation: Non-spring-return, rotary
- Manual override: Included for commissioning and emergency operation
- Position feedback: Integrated 2–10V DC feedback signal
- Overload protection: Electronic, self-resetting
Key Features & Benefits
- Factory-matched valve and actuator combination for simplified installation
- MFT technology allows a single actuator to be configured for multiple control signal types on the job site
- Suitable for heating, cooling, and heat pump systems in commercial buildings
- Reliable Belimo quality with long service life and minimal maintenance
- Compact design integrates easily into existing piping systems
- Ideal for VAV systems, fan coil units, air handling units, and hydronic distribution
Typical Applications
