Armstrong Fluid Technology 571110LF-360 Valve

The Armstrong Fluid Technology 571110LF-360 Valve is a high-precision circuit balancing valve engineered specifically for low flow HVAC applications. This 1/2 inch NPT CBV050VTCR-LF model features a robust brass body with EPDM elastomers, providing exceptional durability and leak-proof performance in demanding environments. Designed for precise hydronic systems management, it offers a flow rate range of 0.26-1.98 GPM, making it ideal for terminal unit balancing. The integrated PT ports allow for rapid pressure and temperature readings, ensuring the 300 PSI maximum working pressure is maintained effectively. With an operating range of -4 to 300 degrees F, this lead-free circuit balancer optimizes energy efficiency by ensuring every zone receives the exact design flow. Utilizing a multi-turn Y-pattern globe style design, the 571110LF-360 provides superior throttling and accurate flow measurement, even at the lowest settings. This genuine Armstrong Fluid Technology component is a critical solution for maintaining occupant comfort and system longevity in commercial and industrial piping networks.

• Enhanced Flow Precision: The multi-turn adjustment handle ensures exact flow regulation between 0.26 and 1.98 GPM for optimized system performance.
• Durable Material Construction: High-grade brass and EPDM elastomers resist corrosion and withstand temperatures up to 300°F.
• Simplified System Diagnostics: Integrated PT ports allow technicians to verify pressure and temperature without breaking the seal.
• Energy Efficiency: Eliminates over-pumping by balancing branch circuits, significantly reducing operational costs.
• Reliable Shutoff: Features a 0% leakage soft seat for positive shutoff during maintenance or isolation.

Is this valve suitable for potable water systems?
Yes, this model carries the NSF-372 lead-free certification, making it safe and compliant for use in potable water applications.

What is the purpose of the "LF" designation in the model number?
The "LF" stands for Low Flow. This specific version is calibrated to accurately measure and balance flow as low as 0.26 GPM, which standard balancing valves cannot do reliably.

Can this valve be installed in any orientation?
While it can be installed in various directions, it is critical to follow the direction-of-flow arrow on the brass body to ensure the venturi and PT ports function correctly.
