Belimo B323+LRB24-SR 1" 3-Way Characterized Control Valve with Actuator

The Belimo B323+LRB24-SR is a complete valve and actuator assembly designed for precise control in hydronic HVAC systems. This package combines a 1-inch brass 3-way characterized control valve with an LRB24-SR proportional spring return actuator for reliable modulating control of heating and cooling applications.

Key Specifications:

• Valve size: 1 inch (DN 25)
• Valve type: 3-way characterized ball valve
• Flow coefficient (Cv): 10
• Actuator: LRB24-SR proportional spring return
• Voltage: 24V AC/DC
• Control signal: 2-10 VDC proportional
• Spring return for fail-safe positioning
• Non-spring return (NSR) override available

Features and Benefits:

• Characterized ball valve design provides linear flow control throughout the valve stroke
• Compact integrated design saves installation time and space
• Spring return actuator ensures fail-safe operation during power loss
• Proportional control delivers precise temperature and flow modulation
• Brass valve body with stainless steel ball for durability and long service life
• Suitable for heating, cooling, and changeover applications

This valve assembly is ideal for use in fan coil units, air handling units, radiant heating/cooling systems, and other commercial HVAC applications requiring accurate flow control and reliable fail-safe operation.
