Armstrong Fluid Technology 571110LF-340 Valve
The Armstrong Fluid Technology 571110LF-340 Valve is a high-performance circuit balancing valve engineered for precise hydronic system regulation. As a direct replacement for 571109-340 and 571110-340, this lead-free brass valve ensures compliance with modern potable water standards while providing exceptional durability. Featuring a 1/2" NPT connection and high-grade EPDM elastomers, the CBV050VTCR model supports a flow rate range of 1.22 to 9.57 GPM. Designed to handle a 300 psi maximum working pressure and operating temperatures from -4 to 300 degrees F, it is ideal for demanding HVACR applications. The integrated PT ports allow for real-time diagnostics and hydronic balancing accuracy, ensuring optimal energy efficiency across the system. Whether you are searching for how to balance a hydronic system or looking for a low lead balancing valve, this Armstrong component provides the reliability required for professional-grade installations.
Key Benefits
- Precision Flow Control: Specifically calibrated to maintain a steady flow rate range, preventing overflow and ensuring system equilibrium.
- Lead-Free Construction: The low lead brass body meets stringent environmental and health regulations for safe water distribution.
- Integrated Diagnostics: Equipped with dual PT ports for easy pressure and temperature measurements without system downtime.
- High Temperature Tolerance: Robust EPDM elastomers allow the valve to operate effectively in extreme thermal environments up to 300°F.
- Direct Compatibility: Seamlessly replaces older Armstrong models, simplifying maintenance and retrofitting tasks.
Common Questions
Can this valve be used in domestic hot water systems?
Yes, the Armstrong 571110LF-340 is constructed from lead-free brass and features a high temperature rating, making it suitable for both HVAC and domestic potable water applications.
What is the purpose of the PT ports on this model?
The PT ports (pressure-temperature) allow technicians to use a manometer or thermometer to verify the system's performance and ensure the circuit balancing is accurate.
Is this a direct fit for the 571110-340?
Yes, the 571110LF-340 is the official direct replacement for the discontinued 571110-340 and 571109-340 units, maintaining the same physical dimensions and 1/2" NPT threading.
