GOODMAN AMANA R-410A Thermal Expansion Valve (TXV) 0151R00197S

GOODMAN AMANA R-410A Thermal Expansion Valve (TXV) 0151R00197S is the current supersession of the discontinued 0151R00197. It precisely meters liquid refrigerant into the evaporator coil for optimal superheat control, system efficiency, and reliable cooling/heat-pump performance.

Key Features

• Official OEM replacement part designed specifically for Goodman and Amana R-410A systems
• Thermostatic Expansion Valve (TXV/TEV) with sensing bulb for responsive, automatic refrigerant flow control
• Optimized for R-410A refrigerant
• Bi-metal construction for durability under typical HVAC operating conditions
• Direct replacement for the earlier 0151R00197 (3-ton Flowrater TXV)
• Factory-new in original packaging

Benefits

• Maintains precise refrigerant metering to prevent overfeeding or underfeeding of the evaporator
• Improves cooling efficiency, temperature consistency, and overall system performance
• Helps protect the compressor by ensuring proper superheat and reducing risk of liquid flood-back or inefficient operation
• Supports higher-efficiency (14+ SEER) systems that require a TXV
• Restores original factory performance when replacing a failed or restricted valve
• Genuine OEM quality ensures proper fit, pressure rating compatibility, and long-term reliability versus generic alternatives

Important: This is not a universal valve. Always verify fitment against your exact outdoor unit, indoor coil, or air handler model number and the manufacturer’s parts list or service manual before ordering. Many TXVs look similar but differ in capacity, orifice, bulb charge, or connection details. Check the unit’s model number (typically on the data plate) and confirm via the supplier’s compatibility tool or OEM documentation.

Common related applications involve Goodman/Amana 3-ton class R-410A split systems and matching cased coils that specify this TXV.

Note: Professional installation is required. Improper installation can damage the system, void warranties, and create safety hazards. Confirm exact compatibility with your equipment model before purchase.
