Belimo B212B Valve

For contractors managing hydronic systems, the Belimo B212B offers a reliable solution for precise flow regulation in demanding HVACR environments. This 1/2 inch 2-way ball valve features a 3.0 Cv rating and is engineered with an equal percentage flow characteristic, ensuring stable control even under light load conditions. Constructed with a nickel-plated forged brass body and a chrome-plated brass ball, the B212B valve is built to withstand chilled or hot water applications with temperatures ranging from 0°F to 250°F. The internal NPT connections provide a secure fit for standard piping, while the TEFZEL characterized disc prevents flow hunt and maintains high close-off pressure up to 200 psi. Compatible with up to 60% glycol solution, this valve is a versatile choice for air handling units, VAV reheat coils, and fan coil units requiring dependable Characterized Control Valve (CCV) performance.

Key Benefits:

• Equal percentage flow characteristic ensures linear heat output and superior control stability.
• 600 psi body pressure rating provides a high safety margin for high-rise and industrial hydronic loops.
• Maintenance-free design with lubricated EPDM O-rings and PTFE seats for extended service life in Building Automation Systems.
• 0% leakage rate (Port A to AB) prevents energy waste and ghost flows in dormant zones.
• Broad compatibility with Belimo LRB, TR, and TFR actuators for flexible field installation.

Common Questions:

What is the maximum glycol concentration for the Belimo B212B?
This valve is rated for hydronic systems utilizing up to a 60% glycol solution, making it suitable for freeze-protection loops.

Can the Belimo B212B be used for steam applications?
No, this specific model is designed for chilled and hot water applications only, with a maximum fluid temperature of 250°F.

Which direction should the B212B be installed?
As a 2-way characterized control valve, it must be installed with the characterized disc on the upstream side to ensure proper flow regulation.
