Belimo B211+TFRB24-SR Valve Assembly
The Belimo B211+TFRB24-SR is a precision-engineered 2-way characterized control valve assembly designed for modulating control in high-performance hydronic systems. This 1/2-inch NPT valve features a stainless steel trim and a 1.9 Cv rating, ensuring durable operation and tight shut-off in air handling units and VAV reheat coils. Paired with a TFRB24-SR spring return actuator, the assembly provides 22 in-lb of torque and reliable fail-safe positioning during power loss. Operating on a 24VAC/DC supply, the modulating actuator responds to a 2-10 VDC control signal, delivering an equal percentage flow characteristic for linear heat output. This CCV (Characterized Control Valve) technology eliminates hunting and stabilizes loop control in variable flow applications. Built for the rigors of commercial HVAC projects, this assembly handles media temperatures from 0°F to 250°F and supports up to 60% glycol concentrations, making it a versatile choice for chilled or hot water transitions.
Key Benefits:- Precision Flow Control: The equal percentage flow characteristic ensures stable temperature regulation and optimal coil performance.
- Industrial Durability: Equipped with a stainless steel ball and stem to resist corrosion and scaling in demanding hydronic loops.
- Reliable Fail-Safe: The spring return actuator guarantees the valve returns to its safety position upon loss of 24V power.
- High Close-Off: Engineered to provide a 200 psi close-off pressure rating, preventing unwanted leakage and energy waste.
- Can this valve be field-adjusted for different control signals? The TFRB24-SR is designed specifically for a 2-10 VDC modulating signal; for other control types, ensure the actuator model matches your BAS requirements.
- Is this assembly suitable for steam applications? No, this Belimo B211 assembly is rated for chilled and hot water or glycol solutions up to 250°F, not for high-pressure steam.
- What is the proper installation orientation for a 2-way CCV? For optimal performance, the valve must be installed with the flow direction following the arrow on the valve body, typically with the characterizing disc upstream.
