The Bard 5651-178BX is a genuine OEM thermal expansion valve (TXV) designed for use in Bard wall-mount and packaged HVAC systems. This precision-engineered component regulates refrigerant flow into the evaporator coil, maintaining proper superheat levels for optimal cooling performance and system efficiency.

Key Features:

• 3/8" x 3/8" ODF (flare) connections for standard refrigerant line compatibility
• Durable brass valve body construction resists corrosion and ensures long service life
• Thermal sensing bulb monitors system conditions and adjusts refrigerant expansion accordingly
• Precise metering prevents overfeeding or underfeeding of refrigerant
• Compatible with common refrigerants including R-22, R-410A, and R-134a
• Factory-boxed OEM replacement part for service and maintenance applications

Replacing a failing or restricted expansion valve can restore proper system capacity, eliminate coil frosting, and correct erratic suction pressure issues. This genuine Bard component ensures proper fit, calibration, and performance matched to your specific HVAC system. Confirm compatibility by matching the part number to your equipment model and serial number before ordering, as expansion valves are system-specific by tonnage and refrigerant circuit design.
