Information About B325+LRB24-SR
The B212B+TFRB24-SR combines a Belimo B212B characterized control valve with a TFRB24-SR spring-return actuator for variable-flow heating and cooling systems. The valve features an equal-percentage flow characteristic, internal-thread connections, and a 600 psi body pressure rating for compatible hydronic applications. Its chrome-plated brass trim is designed for use with chilled or hot water containing up to 60% glycol. The actuator provides modulating 2–10 VDC control, 24 V AC/DC operation, and spring-return functionality for fail-safe positioning.
Key Features:
- 2-Way Valve: Provides two-port flow control for hydronic heating and cooling systems.
- 0.5-Inch Size: Uses a 0.5-inch [15] valve body with internal threaded connections.
- Cv 3: Provides a flow coefficient of 3 for the specified valve configuration.
- Equal-Percentage Flow: Provides an equal-percentage flow characteristic for modulating control.
- Chrome-Plated Brass Trim: Uses chrome-plated brass valve trim for compatible hydronic applications.
- Spring Return: Provides automatic actuator return when operating power is removed.
- Modulating Control: Accepts a DC 2–10 V control signal for proportional valve positioning.
- 24 V Operation: Supports AC/DC 24 V power with 2.5 W running consumption.
The B212B+TFRB24-SR delivers the reliability and precision required for modulating hydronic flow control and fail-safe HVAC valve applications.
