Belimo B261 Valve
The Belimo B261 is a 2 1/2" characterized control valve (CCV) engineered for precise flow regulation in hydronic HVAC units. Featuring a 2-way ball valve design with an equal percentage flow characteristic, this valve is optimized for air handling units, VAV box reheat coils, and fan coil systems. The B261 is constructed with a nickel-plated forged brass body and a stainless steel ball and stem to ensure long-term durability and resistance to scaling in demanding environments. With a 60 Cv rating and a 400 psi body pressure rating, it provides reliable 0% leakage performance (Port A to AB). This NPT female end valve supports chilled or hot water media with temperatures up to 212°F and 60% glycol solutions, making it a standard for professional contractors seeking high-performance Belimo control valves for variable flow systems.
- Precise Flow Control: The equal percentage flow characteristic ensures linear heat transfer in coil applications.
- Corrosion Resistance: Stainless steel trim and a nickel-plated brass body prevent premature wear from harsh hydronic fluids.
- Zero Leakage: Tight close-off pressure rating of 100 psi with 0% leakage maintains system efficiency and prevents thermal energy loss.
- Application Versatility: Suitable for a wide range of HVAC automation setups, including bypass loops and unit ventilators.
Common Questions
What actuators are compatible with the Belimo B261?
The B261 is designed to interface with Belimo ARB and AFRB series actuators, supporting both spring-return and non-spring return configurations for proportional or on/off control.
Is this valve suitable for steam applications?
No, the Belimo B261 is specifically rated for hot and chilled water or glycol solutions up to 212°F. For steam, specialized valves with different seat materials are required.
Can the B261 be installed in any orientation?
While it can be mounted in various positions, it is recommended to install the valve with the characterizing disc upstream and avoid mounting with the actuator below the pipe level to prevent moisture damage.
