Belimo B213B Valve

The Belimo B213B is a precision-engineered 1/2 inch 2-way characterized control valve designed for demanding hydronic HVAC applications. Featuring a 4.7 Cv rating and NPT female connections, this valve utilizes an integrated characterizing disc to provide a true equal percentage flow characteristic. This ensures linear heat transfer in chilled water or hot water systems, preventing the hunting often associated with standard ball valves. The construction consists of a nickel-plated forged brass body, a chrome-plated brass ball, and a nickel-plated brass stem, making it resilient against localized corrosion. Built for longevity in closed-loop systems, it handles up to a 60% glycol solution and operates effectively at temperatures up to 212°F (100°C). For contractors performing retrofits or new installations, the B213B B-Series offers a blowout-proof stem design and a high 0% leakage rate (ANSI Class VI), ensuring optimized pressure drop and superior system stability.

• Optimized Flow Control: The specialized characterizing disc maintains precise control of media, reducing actuator wear and improving thermal efficiency.
• Durable Metallurgy: The forged brass body and chrome-plated ball resist mineral scaling and provide smooth rotation under high differential pressures.
• Wide Compatibility: Standard 1/2" NPT threading allows for seamless integration with commercial piping systems and Belimo LR, AR, or TR actuators.
• High Glycol Tolerance: Engineered to withstand concentrated glycol solutions, making it ideal for freeze-protected water loops.
• Maintenance-Free Performance: Dual EPDM O-rings provide a redundant sealing system that requires no packing adjustments in the field.

What is the maximum close-off pressure for the B213B?
This valve is rated for a close-off pressure of 200 psi, ensuring reliable shut-off in high-head pump applications.

Can this valve be used for steam applications?
No, the B213B is specifically rated for hot and chilled water systems. For steam applications, a different series of stainless steel trim valves should be utilized.

Is this valve compatible with existing Belimo actuators?
Yes, it is designed to pair with non-spring return and spring return actuators, provided the torque requirements of the 2-way body are met.
