Belimo B308+LRB24-SR Characterized Control Valve with Actuator 1/2 Inch 24V

The Belimo B308+LRB24-SR is a characterized control valve assembly combining a 1/2-inch brass valve body with an LRB24-SR spring return actuator for precise HVAC flow control applications.

Key Specifications:

• Valve coefficient (Cv): 0.46 for accurate flow regulation
• Connection size: 1/2-inch NPT threaded
• Actuator: 24V AC/DC, 3-wire configuration
• Control signal: 2-10 VDC modulating input
• Spring return actuator for fail-safe operation
• Characterized flow for linear control response
• Brass valve construction for durability and corrosion resistance

This valve assembly is designed for hydronic heating and cooling systems, providing reliable proportional control with spring return functionality that returns the valve to its normal position upon power loss. The characterized flow design ensures consistent control across the operating range, making it ideal for chilled water, hot water, and glycol solution applications in commercial HVAC systems.
