Belimo B320B+LRB24-SR 3/4" 3-Way Characterized Control Valve with Actuator

The Belimo B320B+LRB24-SR is a characterized control valve assembly combining a 3/4-inch three-way bronze valve body with an LRB24-SR spring return actuator. This compact valve package is designed for precise modulating control in HVAC hydronic systems including heating, cooling, and mixing applications.

Key Specifications:

• Valve size: 3/4-inch NPT threaded connections
• Configuration: 3-way mixing/diverting valve
• Actuator power: 24V AC/DC
• Spring return: Non-spring return (NSR) failsafe operation
• Torque rating: 45 inch-pounds
• Control signal: 2-10 VDC modulating input
• Valve body material: Bronze construction
• Characterized flow: Equal percentage flow characteristic for precise control

Features:

• Direct-coupled actuator and valve assembly for reliable performance
• Modulating control provides accurate temperature regulation
• Compact design suitable for tight mechanical room installations
• Bronze valve body ensures durability and corrosion resistance
• 2-10 VDC control signal compatible with most building automation systems
• Spring return mechanism provides failsafe positioning during power loss

This valve assembly is ideal for mixing valves in heating systems, changeover applications, and general hydronic control where reliable modulating control is required. The characterized valve provides linear control response throughout the operating range.
