Nordyne 920667A TXV Valve
The Nordyne 920667A TXV Valve is a critical thermal expansion device engineered for high-capacity cooling performance in commercial and residential HVAC systems. Designed specifically for R-22 refrigerant, this 6.70-ton expansion valve ensures precise superheat control by modulating mass flow based on evaporator load. This mechanical TXV for Nordyne units utilizes a specialized thermostatic element to maintain system stability, preventing liquid slugging and ensuring the compressor operates within its designed envelope. When replacing an OEM Nordyne expansion valve, verifying the tonnage and refrigerant compatibility is essential for maintaining the rated SEER efficiency and preventing evaporator coil freeze-ups. This heavy-duty valve is a direct fit for specific large-tonnage air handlers and packaged units, providing the reliable pressure drop required for optimized heat transfer. For contractors performing a retrofit or repair, this R22 thermostatic expansion valve offers the durability needed for high-demand cycles and varying ambient conditions.
Technical Specifications and Benefits:
- High-Capacity Metering: Delivers precise 6.7-ton capacity specifically calibrated for R-22 systems.
- Optimized Superheat Control: Consistently manages refrigerant flow to maximize evaporator efficiency across varying load conditions.
- OEM Compatibility: Genuine Nordyne part ensures correct port sizing and bulb placement for a seamless installation.
- System Protection: Acts as a safeguard against compressor damage by preventing unevaporated refrigerant from entering the suction line.
- Durable Construction: Built to withstand commercial-grade pressures and thermal cycling without diaphragm fatigue.
Common Installation and Compatibility Questions:
Is this valve compatible with R-410A systems?
No, the 920667A is strictly designed for R-22 pressure-temperature curves. Using it with R-410A will result in incorrect flow rates and potential system failure.
Does this TXV include the sensing bulb and mounting hardware?
Yes, this assembly includes the integrated sensing bulb required for accurate temperature feedback from the suction line.
What are the symptoms of a failing 6.7-ton TXV?
Technicians typically observe hunting, high superheat readings, or an iced-over evaporator coil when the internal needle or diaphragm fails to modulate correctly.
