Armstrong Fluid Technology 571110LF-342 Valve
The Armstrong Fluid Technology 571110LF-342 Valve (Model CBV100VTCR) is a high-precision 1" NPT circuit balancing valve designed to optimize hydronic system performance in commercial and residential HVACR applications. Built with a durable brass body and high-grade EPDM elastomers, this manual balancing valve ensures reliable fluid control within a 4.57-22.97 gpm flow rate range. Its "Y" pattern globe-style design minimizes turbulence, while the integral fixed orifice provides a stable differential pressure signal for superior measurement accuracy (±5%). Rated for a 300 psi maximum working pressure and an operating temperature range of -4 to 300 degrees F, the Armstrong 571110LF-342 is engineered for longevity. This lead-free balancing valve features PT Ports for easy pressure and temperature readings, along with a multi-turn micrometer handwheel and hidden memory stop to preserve the commissioning setpoint during maintenance or shut-off. Utilizing this HVAC circuit setter prevents over-pumping and ensures balanced heat distribution throughout the building.
Key Benefits- Enhanced System Efficiency: Precisely balances flow to prevent "favored circuits" and reduce energy waste from over-pumping.
- High Measurement Accuracy: The fixed orifice primary measuring element maintains 95% accuracy even at low handwheel settings.
- Durable Construction: Brass body and EPDM seals provide excellent chemical resistance and thermal stability up to 300°F.
- Simplified Maintenance: Features 360-degree multi-turn adjustment and a hidden memory stop to return to the exact balance point after isolation.
- Easy Diagnostics: Integrated PT Ports allow technicians to quickly troubleshoot and verify system flow rates and pressure drops.
How do I set the flow rate on this valve?
The valve uses a micrometer-style handwheel with five full 360-degree turns. Use the provided flow charts or a differential pressure meter connected to the PT Ports to adjust the valve until the desired GPM is reached, then lock the hidden memory stop.
Can this valve be used for potable water?
Yes, the 571110LF-342 is a lead-free (LF) model, making it suitable for both HVAC hydronic systems and potable water applications.
What is the benefit of the "Y" pattern design?
The "Y" pattern globe design reduces internal turbulence compared to standard valves, allowing for more stable flow and more accurate pressure drop readings across the circuit balancing valve.
