Bard CFV-7 Constant Flow Valve 7 Gpm Heat Pump

Product Description

The BARD CFV-7 is a constant flow valve designed for use in geothermal and water-source heat pump systems. It maintains a steady flow rate of 7 GPM through the water loop, regardless of system pressure fluctuations, helping protect the heat exchanger and maintain consistent thermal performance. The valve features 3/4 inch FPT connections for straightforward integration into copper or threaded pipe assemblies. Installation is typically performed by a licensed HVAC technician or plumber familiar with hydronic heat pump loop systems.

This constant flow valve is specified for use with the BARD GV51 heat pump. It is suited for residential or light commercial water-source heat pump installations where maintaining a consistent water flow rate through the refrigerant-to-water heat exchanger is critical to system efficiency and equipment longevity. Proper flow rate control reduces the risk of low-flow faults and helps the system operate within its designed EER range.

Key Features

• Constant flow rate of 7 GPM maintains stable water loop performance
• 3/4 inch FPT connections compatible with standard threaded pipe fittings
• Designed to regulate flow independent of loop pressure variation
• Direct OEM-specified replacement for BARD GV51 heat pump systems

Compatibility

Specified for use with the BARD GV51 heat pump.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber qualified in water-source heat pump systems. Shut off water loop circulation and relieve system pressure before removing or installing the valve. Use thread sealant rated for potable or hydronic water systems on all FPT connections. Verify flow direction markings on the valve body before final assembly.
