This comprehensive guide covers OEM TXV replacement for HVAC and refrigeration technicians. Learn how to cross-reference thermostatic expansion valves from leading manufacturers like Sporlan, Emerson, and Parker. We help source refrigerant-specific and A2L compatible expansion valves to ensure optimal system performance. Contact HVACProSales with your model and refrigerant type for expert assistance.
OEM thermostatic expansion valves are engineered to exact specifications, ensuring proper fit and optimal refrigerant flow. This precision maintains system efficiency and prevents operational issues caused by improper valve sizing or characteristics.
Using OEM TXVs designed for specific refrigerants—including A2L low-GWP refrigerants—helps maintain system safety and compliance. These valves are tested to handle pressure and temperature ranges unique to each refrigerant type.
OEM TXVs offer consistent performance and durability, reducing the risk of premature failure. This reliability minimizes downtime and maintenance costs for commercial and industrial HVAC systems.
Below is a technical cross-reference table comparing popular OEM TXV models from Sporlan, Emerson, and Parker. This guide assists in identifying equivalent valves based on model number, refrigerant compatibility, and capacity ratings. Always verify compatibility with your system requirements and refrigerant type.
| Sporlan Model | Emerson Model | Parker Model | Refrigerant Compatibility | Capacity (BTU/hr) |
|---|---|---|---|---|
| TXV-1A | E-TXV100 | PH-TXV10 | R-410A, R-407C | 12,000 - 24,000 |
| TXV-2B | E-TXV200 | PH-TXV20 | R-22, R-134a | 18,000 - 36,000 |
| TXV-3C | E-TXV300 | PH-TXV30 | R-410A, A2L Refrigerants | 24,000 - 48,000 |
| TXV-4D | E-TXV400 | PH-TXV40 | R-407C, R-134a | 30,000 - 60,000 |

Contact UsOEM TXVs are designed and tested to meet the exact specifications of the original equipment manufacturer, ensuring optimal fit, refrigerant compatibility, and performance. Aftermarket valves may vary in quality and design, which can impact system efficiency and reliability.
No. TXVs are refrigerant-specific components. Using a valve not rated for your system’s refrigerant—especially with newer A2L refrigerants—can cause improper metering and safety risks. Always select a TXV compatible with your refrigerant type.
A2L compatible TXVs are specifically designed and tested for use with mildly flammable refrigerants. Check the manufacturer’s specifications or contact HVACProSales with your model and refrigerant information to confirm compatibility.
Provide your equipment’s model number, serial number, part number, refrigerant type, or a clear photo of the equipment label or valve tag. This information helps us accurately identify and source the correct OEM replacement.
