Belimo B210B+LRB120-3 Valve Assembly

For veteran contractors looking for reliable hydronic flow regulation, the Belimo B210B+LRB120-3 is a purpose-built Characterized Control Valve (CCV) assembly. This kit features a 1/2 inch NPT 2-way valve paired with a rugged non-spring return actuator, delivering a Cv of 1.2. Built with a nickel-plated brass body and chrome-plated brass trim, this assembly is engineered to provide an equal percentage flow characteristic. This ensures linear heat output for heating and cooling coils, making it a staple for VAV box re-heat, fan coil units, and air handling unit bypass loops.

The LRB120-3 actuator operates on a 120V AC power supply, providing 45 in-lb of torque for consistent on/off or floating control. Rated for media temperatures up to 250°F and a 600 psi body pressure, it handles hot water and chilled water systems with up to 60% glycol with ease. The TEFZEL characterizing disc maintains precise flow control, preventing the rapid hunts and surges common in standard ball valves. For technicians, the integrated manual override and NEMA 2/IP54 enclosure ensure straightforward field commissioning and long-term reliability in demanding mechanical rooms.

• Equal Percentage Flow Control: The patented Tefzel characterizing disc prevents oversized valve performance and provides consistent thermal control.
• High Close-Off Pressure: Delivers a 200 psi close-off rating, ensuring no leakage across the PTFE seats in high-pressure hydronic loops.
• Versatile Actuation: The LRB120-3 120V actuator offers non-fail safe operation with a 90-second run time for stable system response.
• Durable Construction: Features nickel-plated brass and EPDM O-rings for compatibility with diverse water treatments.

• What systems is this valve assembly compatible with? It is designed for Building Automation Systems (BAS) managing chilled or hot water applications, including unit ventilators and re-heat coils.
• Does the LRB120-3 actuator have a manual override? Yes, the actuator includes an external push button for manual positioning during startup or power loss.
• Can this be mounted in any orientation? While flexible, it must be installed with the actuator above the horizontal plane of the pipe to prevent condensation from entering the motor.
