Belimo B215B Valve

The Belimo B215B is a 1/2-inch 2-way Characterized Control Valve (CCV) engineered for high-precision modulation in hydronic systems. This 10 Cv ball valve is built with a nickel-plated forged brass body and features a chrome-plated brass ball and stem, ensuring durable performance in demanding environments. Designed specifically for chilled or hot water applications, it handles fluid temperatures up to 212°F and remains stable in systems utilizing up to 60% glycol solutions. The internal Tefzel characterized disc provides an equal percentage flow characteristic, which mimics the linear thermal response of heat exchangers to eliminate "hunting" and stabilize control loops.

For contractors and installers, the Belimo B215B valve offers a 600 psi body pressure rating and use of NPT internal threads for seamless integration into standard piping. The maintenance-free design utilizes EPDM O-rings and PTFE seats, providing 0% leakage from Port A to AB under close-off pressures up to 200 psi. Whether you are regulating fan coil units, air handlers, or VAV reheat coils, this valve provides the reliability necessary for consistent climate control and HVAC system efficiency.

• Precise Flow Control: The equal percentage flow characteristic ensures stable temperature regulation and reduces actuator wear by preventing constant hunting.
• High Media Compatibility: Safely handles chilled and hot water with up to 60% glycol, making it ideal for diverse hydronic HVAC systems.
• Reliable Construction: Features a nickel-plated brass stem and body with a chrome-plated brass ball for long-term corrosion resistance.
• Zero Leakage: Tight shut-off rating of 0% for A-AB ensures no energy waste during idle periods.
• Versatile Installation: Standard 1/2" NPT connections allow for straightforward field replacement in AHUs, FCUs, and unit ventilators.

What actuators are compatible with the B215B?
This valve is designed for use with Belimo non-fail safe (TR, LRB) and spring return (TFRB, LF) actuators. Proper selection depends on your torque and fail-safe requirements.

Can this valve be used for steam applications?
The B215B is rated for chilled and hot water applications up to 212°F. It is not suitable for steam service; for those applications, consult specifications for Belimo's steam-rated globe or ball valves.

What is the proper flow orientation for the B215B?
For optimal performance, 2-way valves should be installed so that the fluid flows into the port with the characterizing disc (upstream) to maintain the intended flow characteristic.
