Belimo G315B-G+NFB24-SRX1 Globe Valve with Actuator Cv - 1/2 3-Way 2.2 24V

The Belimo G315B-G+NFB24-SRX1 is a complete valve and actuator assembly designed for precise control in HVAC hydronic systems. This unit combines a 1/2-inch 3-way brass globe valve with a spring return actuator for reliable modulating control of hot or chilled water flow.

Key Specifications:

• Valve Size: 1/2 inch NPT threaded connections
• Configuration: 3-way mixing/diverting globe valve
• Flow Coefficient (Cv): 2.2
• Actuator: NFB24-SR proportional control
• Power Supply: 24V AC/DC
• Control Signal: Proportional modulating control (typically 0-10V or 2-10V)
• Spring Return: Fail-safe spring return to normal position on power loss
• Valve Body Material: Brass construction for durability

This assembly is ideal for zone control, bypass applications, and mixing applications in commercial and residential HVAC systems. The proportional actuator provides smooth, accurate control with minimal hysteresis, while the spring return feature ensures safe positioning during power failures. Factory-assembled and tested for immediate installation.
