Belimo B347+ARB24-3 2-Inch NPT Characterized Control Valve with Actuator

The Belimo B347+ARB24-3 is a high-performance characterized control valve assembly designed for precise flow control in commercial HVAC systems. This package combines a rugged stainless steel valve body with an integrated 24V electronic actuator for reliable, modulating control of heating and cooling water applications.

Key Specifications:

• 2-inch NPT threaded connections for easy installation
• Cv rating of 29 for excellent flow capacity
• Stainless steel valve body construction for durability and corrosion resistance
• 24V actuator with non-spring return (NSR) operation
• 2-position control with floating action
• Includes integrated fault detection capability
• Characterized control for linear response throughout the valve stroke

This valve assembly is ideal for chilled water, hot water, and dual-temperature applications in variable air volume (VAV) systems, fan coil units, and other hydronic HVAC equipment. The non-spring return actuator maintains valve position during power loss, while the 2-position floating control provides precise modulation based on control signals. The stainless steel construction ensures long service life even in demanding water quality conditions.
