Belimo B220+LF120 Valve Assembly

The Belimo B220+LF120 Valve Assembly is a high-performance hydronic solution combining a 3/4" 2-way Characterized Control Valve (CCV) with a robust LF120 spring return actuator. Engineered for demanding HVAC applications, this NPT valve assembly features stainless steel trim and a Cv rating of 14, making it ideal for the precise regulation of chilled or hot water in air handling units and fan coil systems. The integrated 120Vac on/off control actuator provides 35 in-lb torque, ensuring reliable fail-safe operation during power interruptions. Utilizing a patented characterizing disc, this assembly delivers an equal percentage flow characteristic, which prevents control loop hunting and significantly improves thermal stability compared to standard ball valves. Constructed with a forged brass body rated for 600 psi and NEMA 2 protection, this setup is designed for long-term durability in commercial mechanical rooms.

• Precise Flow Control: The characterizing disc ensures equal percentage flow, mimicking globe valve performance for superior part-load stability.
• Reliable Fail-Safe: True spring return logic ensures the valve returns to its safe position immediately upon loss of 120V power.
• Corrosion Resistance: High-grade stainless steel ball and stem prevent scale buildup and extend service life in treated water systems.
• Simplified Installation: Features a direct-coupled design with a universal shaft clamp, reducing the need for complex linkages or brackets.
• Zero Leakage: The bubble-tight shut-off design prevents energy waste and ghost heating in inactive coils.

What is the maximum fluid temperature for the B220?
This assembly is rated for chilled or hot water and 60% glycol solutions with a fluid temperature range of 0°F to 250°F (-18°C to 120°C).

Can the LF120 actuator be mounted in any orientation?
The actuator can be mounted in four different positions, though it is recommended to avoid mounting with the actuator underneath the valve to prevent moisture damage from condensation.

Does this assembly require a specific mounting kit?
No, the B220+LF120 is a factory-assembled unit that includes the necessary linkage for direct-coupled on/off fail-safe operation.
