The characterized valve design provides a predictable equal percentage flow response, improving control accuracy across varying load conditions. Fitted with a non-fail-safe TR24 actuator, the assembly supports smooth modulating operation and low power consumption for continuous control applications. This valve-actuator combination is commonly used in terminal units, fan coil systems, and small heating or cooling circuits within commercial buildings. Key Features Characterized Control Valve Design: Provides an equal percentage flow characteristic that improves control stability and accuracy across the full operating range. Integrated Valve and Actuator Assembly: Factory-fitted configuration ensures proper mechanical alignment, reliable performance, and simplified installation. Non Spring Return Actuation: Supports continuous modulating control where fail-safe positioning is not required, reducing mechanical complexity. 2–10 V Modulating Control: Enables precise proportional flow control with optional 4–20 mA capability for flexible integration with automation systems. Low Power Consumption: Operates at just 0.5 W, supporting energy-efficient system design and reduced operating costs. Manual Override Handle: Allows direct manual positioning during commissioning, testing, or maintenance without electrical power. Tight Shutoff Performance: Achieves 0% leakage for A–AB ports, supporting accurate flow isolation and improved system efficiency. The B211B+TR24-SR-T US delivers the reliability and precision required for accurate modulating hydronic flow control in commercial HVAC applications.
