Bard HVAC 5651-077 TXV
The Bard HVAC 5651-077 Thermostatic Expansion Valve (TXV) is a critical metering device engineered for precise refrigerant flow control in 2.5 ton air conditioning and heat pump systems. Designed with 3/8" x 3/8" ODF solder connections, this valve ensures a leak-free integration into the liquid line. It functions by monitoring evaporator superheat, adjusting the orifice to match the cooling load, which prevents liquid slugging and protects the hermetic compressor. This specific Bard OEM replacement TXV is balanced to maintain system efficiency across varying ambient temperatures, making it a reliable choice for maintaining SEER ratings during field repairs or component upgrades.
Key Benefits- Optimized Refrigerant Metering: Maintains consistent evaporator superheat levels to maximize heat transfer efficiency.
- Durable Construction: Built with high-grade materials to withstand high-pressure R-410A refrigerant cycles.
- OEM Compatibility: Precision-engineered for Bard wall-mount units and 2.5 ton HVAC systems, ensuring direct fitment without piping modifications.
- System Protection: Actively prevents refrigerant floodback, extending the service life of the cooling coil and compressor.
What are the connection sizes for the Bard 5651-077?
This valve features 3/8 inch ODF (Over Design Flow) sweat connections for both the inlet and outlet, requiring standard brazing techniques for installation.
Is this TXV compatible with R-22 or R-410A systems?
The Bard 5651-077 is specifically calibrated for R-410A systems. Always verify the refrigerant type on the unit nameplate before installation to ensure proper pressure-temperature (PT) characteristics.
Can this 2.5 ton TXV be used on a 2 ton system?
It is recommended to match the TXV tonnage exactly to the evaporator coil capacity. Using a 2.5 ton valve on a smaller system may lead to hunting and unstable superheat readings.
