Bard HVAC 5651-094BX Expansion Valve

The Bard HVAC 5651-094BX Expansion Valve is a critical thermal expansion device engineered for precise refrigerant metering in R-22 HVAC systems. This 1-ton capacity expansion valve features a 3/8-inch inlet and 3/8-inch outlet, providing the correct pressure drop to ensure optimal evaporator coil saturation. As the direct replacement for the legacy Bard 5651-094, the 5651-094BX is specifically designed for integration with the Bard WH183-A Wall-Mounted Package Heat Pump. By accurately regulating refrigerant flow control based on cooling load, this component prevents liquid slugging of the compressor and eliminates uneven cooling or coil icing. For technicians performing maintenance or emergency repairs on Bard wall-mount units, this OEM valve ensures the system operates within original factory superheat specifications, maintaining high-side and low-side pressure balance across the refrigeration cycle.

Key Benefits for Contractors

• Direct OEM Replacement: Replaces Bard 5651-094 with exact fitment, reducing labor time during field installation.
• R-22 Compatibility: Specifically calibrated for R-22 refrigerant properties to maintain system efficiency.
• System Reliability: Prevents evaporator flood-back and stabilizes superheat levels in Bard WH183-A unit repairs.
• Precise Metering: A 1-ton nominal capacity ensures accurate refrigerant dosing, critical for small tonnage wall-mount applications.
• Standard Connections: 3/8" x 3/8" configuration allows for standard brazing or fitting procedures common in HVACR service.

Common Questions

Is the 5651-094BX compatible with R-410A systems?
No, this expansion valve is specifically designed and calibrated for R-22 refrigerant. Using it with R-410A will lead to incorrect metering and potential system failure.

Does this valve include the internal check valve for heat pump applications?
Yes, as a Bard HVAC replacement part for the WH183-A heat pump series, it is designed to handle the flow requirements of the refrigeration cycle in both heating and cooling modes.

Can I use this valve on a 1.5-ton or 2-ton unit?
This is a 1-ton capacity expansion valve. Installing it on a system with a higher tonnage rating will result in an undersized orifice, causing high superheat and starving the evaporator.
