Belimo B210B+TR24-SR-T Proportional Control Valve Cv - 1/2 2-Way 24V 1.2

The Belimo B210B+TR24-SR-T is a compact 1/2-inch two-way control valve assembly designed for precise HVAC zone control and hydronic balancing applications. This actuated valve combines a brass valve body with a TR24-SR-T proportional actuator for reliable modulating control in commercial and light industrial systems.

Key Features:

• 1/2-inch NPT threaded connections for easy installation in small zone applications
• Two-way normally closed configuration for fail-safe operation
• 1.2 Cv flow coefficient provides precise flow control for terminal units
• Non-spring return actuator with 24V AC/DC power supply
• 2-10 VDC proportional control signal for modulating operation
• 35 in-lbs (4 Nm) actuator torque ensures positive valve closure
• Compact design suitable for tight mechanical spaces and zone valve boxes
• Lead-free brass construction meets NSF/ANSI 372 and NSF/ANSI 61 standards

This valve assembly is ideal for chilled and hot water systems, radiant heating and cooling, fan coil units, unit heaters, and other hydronic terminal equipment requiring precise temperature control. The proportional control allows for smooth modulation and reduced system cycling, improving occupant comfort and energy efficiency.
