Amana-Goodman TX5N4 Valve Kit

The Amana-Goodman TX5N4 Thermal Expansion Valve (TXV) Kit is a critical metered orifice replacement engineered specifically for R-410A refrigerant systems. This non-bleed, bolt-on expansion valve is designed to optimize superheat by precisely regulating refrigerant flow into the evaporator coil, ensuring high-efficiency heat transfer across varying load conditions. As a direct replacement for BT1369070S, the TX5N4 valve kit is compatible with 1.5 to 5-ton Goodman, Amana, and Janitrol air conditioners and heat pumps. Utilizing a hard shut-off TXV design, this kit improves seasonal energy efficiency ratios (SEER) and prevents liquid slugging during off-cycles. The inclusion of the internal check valve facilitates bi-flow operation, making it essential for heat pump applications. For contractors performing a HVAC TXV replacement, this kit provides a field-installable solution to address hunting issues or restricted flow, restoring factory-spec subcooling and pressure drops across the high-side liquid line.

• Optimized Superheat Control: Maintains precise refrigerant metering to maximize evaporator efficiency and compressor longevity.
• Direct OEM Compatibility: Engineered as a drop-in replacement for part number BT1369070S, ensuring exact mechanical fit.
• R-410A Specific Design: Pressure-rated and calibrated specifically for use with 410A high-pressure systems.
• Improved System Efficiency: Enhances SEER ratings and prevents compressor damage by maintaining consistent evaporator saturation temperatures.
• Bi-Flow Capability: Integrated check valve allows for seamless operation in both cooling and heating modes for heat pump systems.

What symptom indicates a failing TX5N4 valve?
Technicians often observe low suction pressure, high superheat, and normal-to-high subcooling, indicating a restricted or stuck-closed TXV orifice.

Is the TX5N4 a bolt-on or sweat-fit valve?
The TX5N4 TXV kit is a bolt-on design, utilizing mechanical fittings to simplify field installation without the need for extensive brazing near sensitive internal components.

Can this valve be used on R-22 systems?
No, this valve is specifically calibrated for the pressure characteristics of R-410A refrigerant and should not be used in legacy R-22 equipment.
