Overview
The Belimo B208+LF24-MFT-S US combines a 1/2″ low-flow characterized control valve with a programmable spring-return actuator and an integrated auxiliary switch. It ensures tight shut-off, accurate flow control, and fail-safe safety.
Features
- Low Cv design ideal for low-flow hydronic control loops
- Programmable Multi-Function Technology (MFT) for tailored control and feedback
- Built-in SPDT auxiliary switch for end-point signaling or auxiliary equipment interlocks
- Spring-return fail-safe action returns valve to safe position during power failures
Specifications
- Valve Size: 1/2″ NPT
- Flow Coefficient (Cv): 0.46
- Nominal Voltage: AC/DC 24 V
- Auxiliary Switch: 1 x SPDT
- Control Signal: 2-10 V (MFT/programmable)
Applications
- Precision chilled and hot water control in terminal units
- VAV box reheat coils and unit ventilators needing end-switch status
- Hydronic systems requiring low-flow precision and fail-safe operation
