Belimo B208B+LF24-SR Control Valve with Spring Return Actuator - 1/2 2-Way

The Belimo B208B+LF24-SR is a compact characterized control valve (CCV) assembly designed for precision HVAC control applications. This valve combines a 1/2" NPT two-way brass valve body with an integrated 24V spring return actuator, providing reliable modulating control for heating and cooling systems.

Key Specifications:

• Valve size: 1/2" NPT female connections
• Configuration: 2-way characterized control valve
• Flow coefficient (Cv): 0.46
• Actuator: LF24-SR with spring return fail-safe positioning
• Power supply: 24V AC/DC
• Control signal: 2-10 VDC modulating
• Close-off pressure: 35 PSI
• Spring return provides fail-safe closure on power loss

This valve assembly is ideal for small zone control applications, fan coil units, unit heaters, and other HVAC systems requiring precise flow modulation. The characterized valve design ensures linear flow control throughout the operating range, while the spring return actuator provides reliable fail-safe operation for system safety.
