Belimo B211 Valve
The Belimo B211 is a high-performance 1/2 inch NPT 2-way characterized control valve designed for precision in HVAC hydronic systems. Featuring a 1.9 Cv rating, this valve utilizes a specialized equal percentage flow characteristic, made possible by a built-in Tefzel characterizing disc. This design compensates for the non-linear heat transfer of coils, ensuring stable modulating control and preventing system hunting. The unit is constructed with a nickel-plated forged brass body and a 304 stainless steel ball and stem, making it resilient against the high-torque demands of chilled or hot water applications. Rated for media temperatures up to 212°F and capable of handling up to 60% glycol solutions, the B211 is a reliable choice for contractors managing air handling units and VAV reheat coils. Its blowout-proof stem design and EPDM O-rings provide a leak-proof seal under high static pressures.
Key Benefits for Technicians- Corrosion Resistance: The stainless steel trim prevents scale buildup and pitting, ensuring long-term seat integrity in closed-loop hydronic systems.
- Precision Flow Control: The equal percentage insert eliminates the typical "jump" in flow associated with standard ball valves, providing smoother BMS integration.
- High Close-off Pressure: Engineered to handle high differential pressures without leakage, maximizing energy efficiency across the loop.
- Universal Compatibility: Standard NPT threading allows for seamless pairing with Belimo LR and TR series actuators for field replacement or new installs.
- Zero Maintenance Design: The chrome-plated or stainless ball reduces friction, extending the life of the actuator motor by reducing operating torque requirements.
What is the maximum pressure drop allowed for the Belimo B211?
To maintain laminar flow and prevent cavitation/noise, it is recommended to keep the differential pressure drop below 25-30 PSI for water applications.
Can the B211 be installed in any orientation?
The valve can be mounted vertically or horizontally. However, it should not be installed with the actuator hanging below the valve body to prevent moisture from entering the motor housing.
Which actuators are compatible with this 1/2" control valve?
The B211 is compatible with Belimo LRB, TR, and ARB series actuators. Always verify the close-off pressure requirements of your specific system before selecting the torque rating of the actuator.
