Belimo B223+LF24 Valve Assembly
The Belimo B223+LF24 Valve Assembly is a high-performance 1-inch NPT characterising control valve designed for precision in hydronic systems. This 2-way ball valve features a stainless steel ball and stem, ensuring durability against corrosive elements and scale buildup. With a Cv of 10, the B223 utilizes a specialized characterizing disc to provide a true equal percentage flow characteristic, eliminating the hunting common in standard ball valves. Paired with the LF24 spring return actuator, this assembly delivers 35 in-lb of torque and operates on a standard 24VAC/DC power supply. The spring return fail-safe mechanism ensures the valve returns to its home position during power loss, protecting heat exchangers and coils. Engineered for on/off control in AHUs and fan coil units, this assembly provides a zero-leakage close-off pressure of 200 psi, making it a reliable solution for demanding commercial HVAC environments where tight shut-off and consistent flow control are non-negotiable.
Key Benefits
- Equal Percentage Flow: The integrated characterizing disc allows for precise linear heat output, optimizing HVAC hydronic control.
- Fail-Safe Operation: The LF24 actuator provides mechanical spring return for reliable system protection during outages.
- Superior Close-off: Rated for zero leakage at high differential pressures, preventing unwanted energy transfer.
- Rugged Construction: Stainless steel trim and a fiberglass-reinforced Teflon seat ensure longevity in chilled or hot water applications.
- Ease of Installation: Standard NPT female threading and a universal 24V actuator footprint simplify field replacement and retrofitting.
Common Questions
What is the maximum fluid temperature for the B223+LF24?
This assembly is typically rated for media temperatures ranging from 0°F to 250°F (-18°C to 120°C), making it suitable for both chilled water and low-pressure steam applications.
Can the LF24 actuator be mounted in any orientation?
The assembly should be mounted with the actuator stem in the vertical position or horizontal; it is not recommended to mount the actuator upside down to prevent moisture from entering the housing.
Is this valve suitable for glycol-based systems?
Yes, the Belimo CCV series is compatible with up to 60% glycol concentrations, provided the fluid remains within the specified temperature limits.
