Need help confirming the correct valve? Use the TXV cross-reference guide and request verification assistance. Always match the exact refrigerant, capacity, connection, and equipment requirements.
How to select and verify a TXV replacement
A thermostatic expansion valve meters refrigerant into the evaporator in response to operating conditions, but a replacement must be selected for the specific system and application. Nominal capacity or refrigerant alone does not establish interchangeability.
| Selection check | What to verify |
|---|---|
| System and refrigerant | Approved refrigerant, evaporator application, operating range, and manufacturer requirements. |
| Capacity and conditions | Valve capacity at the actual evaporating temperature, condensing temperature, liquid temperature, and pressure-drop conditions. |
| Valve configuration | Internally or externally equalized design, thermostatic charge, connection type and size, flow direction, and physical fit. |
| Original identification | Complete valve model, equipment model and serial number, element markings, and any approved manufacturer cross-reference. |
Confirm selection against current manufacturer data before installation. Bulb location, equalizer routing, brazing practices, adjustment, and system charging can affect operation; diagnose the system rather than assuming the valve is the cause of a symptom. Review Parker Sporlan's TXV application and service literature, browse the Sporlan valve selection, or use the appropriate HVAC service tools.
