Belimo B240+ARB24-3 Valve Assembly

The Belimo B240+ARB24-3 is a heavy-duty 1 1/2" NPT 2-way charactering control valve (CCV) assembly engineered for high-demand hydronic systems. This unit features a stainless steel ball and stem to ensure long-term reliability in chilled or hot water applications, preventing the premature pitting often seen with inferior alloys. The integrated ARB24-3 non-spring return actuator delivers 180 in-lb of torque, providing precise control for floating and on/off signals at 24V AC/DC. With a Cv rating of 37, this Belimo valve assembly maintains consistent flow rates while the patented characterising disc ensures a true equal percentage flow characteristic. This design eliminates hunting in the control loop, extending the service life of the HVAC actuator and improving overall thermal efficiency in commercial air handling systems and terminal units. Designed for easy installation, the assembly utilizes a standard ISO mount for straightforward field maintenance and commissioning.

• Enhanced Durability: The stainless steel trim and ball minimize corrosion and scale build-up in harsh fluid environments.
• Operational Stability: Specifically designed charactering control valve disc ensures linear system response and stable room temperature control.
• Reduced Leakage: Features a zero-percent leakage rating, preventing energy loss during on/off control cycles.
• Versatile Power Options: The 24V actuator accepts both 24Vac and 24Vdc inputs for flexible integration into existing BAS architectures.

What is the maximum close-off pressure for this 1 1/2" valve?
The B240 series provides a close-off pressure of 200 psi, ensuring reliable shut-off in high-head applications.

Can the ARB24-3 actuator be manually overridden?
Yes, the actuator features a manual override button on the housing to allow for positioning during power loss or system testing.

Is this assembly suitable for steam applications?
No, the Belimo B240+ARB24-3 is rated for chilled and hot water with up to 60% glycol; it is not intended for steam service.
