Belimo B212 Valve

The Belimo B212 is a high-performance 1/2" 2-way characterized control valve engineered for precise modulation in chilled or hot water HVAC systems. This NPT ball valve features a 3.0 Cv rating and utilizes a specialized disc to provide an equal percentage flow characteristic, ensuring stable control loop linear performance. Built for demanding mechanical rooms, the B212 valve is constructed with a nickel-plated forged brass body and a stainless steel ball and stem, offering superior durability over standard brass trim. It is rated for 600 psi (body pressure) and can handle fluid temperatures up to 212°F, making it compatible with up to 60% glycol solutions. This HVAC ball valve is an industry standard for hydronic applications requiring reliable shut-off and accurate throttling, easily pairing with Belimo rotary actuators for seamless automation.

• Optimized Control: The equal percentage flow design eliminates "hunting" by providing consistent temperature control.
• Corrosion Resistance: The stainless steel trim ensures longevity when exposed to aggressive hydronic fluids and high glycol concentrations.
• Leak Prevention: Features a double O-ring design for maintenance-free operation and zero percent leakage through the port.
• Flexibility: Designed for an internal thread NPT connection, allowing for rapid field installation into existing piping frameworks.
• High Pressure Rating: A 600 psi rating ensures the assembly maintains integrity in high-rise or large-scale commercial loops.

What is the maximum glycol percentage for the B212?
This valve is designed to handle up to a 60% glycol solution, making it suitable for freeze-protection loops and industrial cooling.

Can I use this for steam applications?
No, the Belimo B212 is rated for chilled and hot water systems. For steam, you must specify a high-temperature steam-rated valve.

Is this valve a bubble-tight shut-off?
Yes, the A-port provides 0% leakage, ensuring complete isolation when the actuator is in the closed position.
