Belimo B218+LRB24-3 Valve Assembly

The Belimo B218+LRB24-3 Valve Assembly is a high-performance 3/4 inch 2-way Characterized Control Valve (CCV) solution designed for precise hydronic regulation in air handling and fan coil units. This assembly features a rugged stainless steel trim and ball, ensuring superior corrosion resistance and longevity in demanding HVACR environments. With a Cv of 7.4 and an equal percentage flow characteristic, it provides the throttling accuracy typically reserved for more expensive globe valves while maintaining the high close-off capabilities of a ball valve.

Powered by the LRB24-3 non-spring return actuator, this ensemble delivers 45 in-lb of torque for reliable on/off or floating point control. Operating on a 24Vac/dc power supply, it is engineered for seamless integration into existing building automation systems. The specialized characterizing disc prevents control loop hunting and reduces wear on downstream components, making it an essential pick for technicians managing variable flow systems. Its NPT internal thread connection allows for straightforward field installation without complex piping modifications.

Key Benefits:

• Stainless Steel Ball and Stem: Enhanced durability and chemical resistance compared to standard brass components.
• Equal Percentage Flow: Provides linear heat output for optimized coil performance and energy efficiency.
• High Close-Off Pressure: Rated for 200 psi close-off to prevent leakage and thermal ghosting in inactive zones.
• Maintenance-Free Design: Features an EPDM O-ring and PTFE seats, eliminating the need for regular packing adjustments.
• Versatile Control: Supports on/off or 3-point floating signals to match various controller requirements.

Common Questions:

What is the maximum fluid temperature for this assembly?
The valve body is rated for fluid temperatures ranging from 0°F to 250°F (-18°C to 120°C), making it suitable for both chilled water and hot water applications with up to 60% glycol.

Can I install this valve in any orientation?
While the valve can be mounted in multiple positions, it must be installed with the characterizing disc on the upstream side. The actuator should not be mounted below the horizontal plane to prevent moisture buildup in the housing.

Does this assembly provide fail-safe operation?
No, the LRB24-3 is a non-fail safe actuator. It will maintain its last position upon loss of power. For applications requiring a normally open or normally closed fail-safe position, a spring-return model would be required.
