Belimo B313B+LRB24-SR 1/2" 3-Way Characterized Control Valve with Actuator

The Belimo B313B+LRB24-SR is a complete characterized control valve assembly combining a 1/2" brass 3-way valve body with an LRB24-SR proportional actuator. This compact valve package is designed for precision control in hydronic HVAC systems, offering reliable modulating control for heating and cooling applications.

Key Features:

• 1/2" NPT threaded connections for easy installation
• 3-way valve configuration for mixing or diverting service
• 4.7 Cv flow coefficient for optimal system performance
• 24V proportional spring return actuator with non-spring return (NSR) failsafe
• Characterized valve plug for linear control characteristics
• Brass valve body construction for durability and corrosion resistance
• Factory assembled and tested for reliable operation
• Suitable for water and glycol solutions in HVAC systems

This valve assembly provides precise flow control in heating and cooling coils, fan coil units, and other hydronic equipment. The proportional actuator responds to modulating control signals, allowing for accurate temperature control and energy-efficient operation. The characterized valve design ensures consistent control throughout the operating range.
