Overview
The Belimo B208+LF24-MFT US is a 1/2″ 2-way characterized control valve assembly designed for precise low-flow regulation in HVAC applications. It pairs a low-Cv valve with a programmable spring-return actuator for maximum efficiency and system protection.
Features
- Ultra-low flow coefficient (Cv 0.46) for high-precision temperature control in small loops
- Multi-Function Technology (MFT) allows custom runtime, control range, and feedback signals
- Spring return fail-safe mechanism operates during power supply disruptions
- Maintenance-free operation with electronic overload protection
Specifications
- Valve Size: 1/2″ NPT
- Flow Coefficient (Cv): 0.46
- Nominal Voltage: AC/DC 24 V
- Control Signal: 2-10 V (MFT/programmable)
- Torque: 35 in-lb [4 Nm]
Applications
- Small terminal units, VAV box reheat coils, and unit ventilators
- Chilled or hot water systems with low flow requirements
- Precision zone temperature control in commercial facilities
