Belimo B210B Valve

The Belimo B210B Valve is a 1/2-inch 2-way characterized control valve engineered for precision in hydronic systems. Designed for both chilled and hot water applications, this valve handles media temperatures up to 212°F and 60% glycol solutions with a 600 psi body pressure rating. It features a high-performance nickel-plated forged brass body coupled with a chrome-plated brass ball and a nickel-plated brass stem. The integrated equal percentage flow characteristic is achieved via a dedicated Tefzel characterizing disc, preventing control loop hunting and ensuring stable thermal output in air handling units and fan coil systems. With a 1.2 Cv rating and a maintenance-free design that eliminates the need for repacking, the B210B provides a zero-leakage seal (A to AB) and a close-off pressure of 200 psi. This NPT female threaded valve is compatible with various LR, TR, and TFR actuators, making it a versatile choice for VAV box reheat coils and unit ventilators.

• Precise Control: The specialized equal percentage flow curve provides linear heat output, optimizing energy consumption in variable flow systems.
• Industrial Durability: Constructed with a forged brass body and EPDM lubricated O-rings to endure demanding HVAC environments.
• Zero Leakage: Internal PTFE seats and a chrome-plated ball ensure bubble-tight shutoff, increasing system efficiency and reducing ghost energy loads.
• Application Versatility: High temperature and glycol tolerance make it suitable for a wide range of heating and cooling coil configurations.

What is the maximum glycol concentration for this valve?
The B210B is rated for up to 60% glycol solution, making it ideal for systems requiring significant freeze protection.

Can I install this valve in any orientation?
While the valve can be mounted in various positions, it must be installed with the characterizing disc upstream to ensure the specified flow characteristics are met.

What is the close-off pressure rating?
This 1.2 Cv valve provides a 200 psi close-off pressure, ensuring reliable performance in high-head pumping applications.
