Description
The Goodman 0151M00078 is an OEM thermostatic expansion valve (TXV) engineered for use with R410A refrigerant in 5-ton residential and light commercial cooling systems. Designed as a direct replacement for compatible Goodman and Amana-brand equipment, this TXV precisely meters refrigerant flow into the evaporator coil, maintaining optimal superheat levels and maximizing system efficiency throughout varying load conditions.
Key Features
- OEM Goodman replacement TXV for accurate, reliable fit
- Compatible with R410A refrigerant systems
- Rated for 5-ton (60,000 BTU/hr) capacity applications
- Maintains precise superheat control for maximum system efficiency
- Helps protect the compressor from liquid slugging and overheating
- Engineered for consistent performance across varying load conditions
- Direct drop-in replacement — minimizes installation time and labor
What Is a TXV?
A thermostatic expansion valve (TXV) is a refrigerant metering device that automatically adjusts refrigerant flow to the evaporator based on real-time superheat measurements. Unlike fixed orifice devices, a TXV continuously modulates flow to match the system’s cooling load, improving efficiency, protecting the compressor, and extending overall equipment life.
Applications
- Goodman and Amana split-system air conditioners and heat pumps
- 5-ton R410A residential and light commercial HVAC systems
- Replacement of failed or underperforming OEM TXV components
Why Choose OEM?
Using a genuine Goodman OEM TXV ensures compatibility with your system’s design specifications, preserving manufacturer warranties and delivering the performance your equipment was built to achieve. Aftermarket substitutes may not meet the precise flow and pressure ratings required for reliable operation.
