Belimo B211+LRB24-3 Characterized Control Valve 1/2" Ball Valve 24V

The Belimo B211+LRB24-3 is a 1/2" characterized control ball valve with integrated 24-volt non-spring return actuator, designed for precise flow control in HVAC hydronic systems. This compact assembly combines a brass ball valve body with an electric actuator to deliver reliable modulating control for heating and cooling applications.

Key Specifications:

• Valve size: 1/2 inch nominal pipe size
• Flow coefficient (Cv): 1.9
• Actuator voltage: 24V AC/DC
• Actuator type: Non-spring return (NSR) - remains in position on power loss
• Valve body: Brass construction with characterized ball for linear flow control
• Connection type: Threaded female NPT ends
• Compact design suitable for tight installation spaces

This pre-assembled valve and actuator package is ideal for chilled water, hot water, and glycol solutions in commercial HVAC systems. The characterized ball provides consistent control across the flow range, while the non-spring return actuator maintains position during power interruptions for fail-in-place operation.
