Belimo B214B+LRB24-SR-T Characterized Control Valve with Non-Spring Return Actuator - 1/2 2-Way

The Belimo B214B+LRB24-SR-T is a complete characterized control valve assembly designed for precision flow control in HVAC systems. This compact assembly combines a 1/2" NPT brass valve body with an integrated 24V modulating actuator for reliable performance in heating, cooling, and process control applications.

Key Specifications:

• Valve size: 1/2" NPT threaded connections
• Configuration: 2-way characterized control valve (CCV)
• Flow coefficient (Cv): 7.4
• Valve body material: Brass construction for durability and corrosion resistance
• Actuator type: LRB24-SR-T non-spring return, proportional modulating
• Power supply: 24V AC/DC operation
• Control signal: Modulating (proportional) control for precise flow regulation
• Non-spring return: Remains in last position on power loss

Features and Benefits:

• Characterized valve design provides linear flow control for accurate temperature regulation
• Compact, direct-mount actuator eliminates need for linkages and brackets
• Non-spring return design ideal for fail-in-place applications
• Modulating control allows precise positioning anywhere from 0-100% open
• Brass body suitable for water, glycol solutions, and compatible fluids
• Factory-assembled and tested for plug-and-play installation

This valve assembly is commonly used in fan coil units, unit heaters, chilled beams, radiant heating/cooling systems, and other applications requiring precise flow modulation. The compact 1/2" size makes it ideal for smaller zone control applications and retrofit installations where space is limited.
