Nordyne 664350 TXV Valve
The Nordyne 664350 is a high-performance 4-ton R410A thermostatic expansion valve engineered for precise refrigerant metering in residential and light commercial split-system evaporators. This genuine OEM component is designed to maintain target superheat across varying load conditions, protecting the compressor from liquid slugging while maximizing heat transfer efficiency. As a direct replacement for Nordyne 664350R, it features a balanced port design that compensates for head pressure fluctuations commonly found in high-SEER configurations. The valve utilizes a mechanical pressure-sensing element to modulate flow, ensuring the evaporator coil remains fully active without overfeeding. For technicians performing a HVAC TXV replacement, this bolt-on or sweat-in solution provides the reliability required for 410A systems. Integrating this 4-ton expansion valve into Nordyne air handler parts or coil assemblies ensures the system operates within manufacturer-specified parameters, stabilizing suction pressure and improving overall dehumidification cycles during peak thermal demand.
Key Technical Benefits
- Optimized Refrigerant Control: Specifically calibrated for 4-ton R410A systems to ensure precise evaporator saturation.
- Direct OEM Fit: Serves as the factory-authorized Nordyne 664350R replacement for seamless installation.
- System Reliability: Prevents compressor damage by maintaining consistent superheat under diverse ambient temperatures.
- Enhanced Efficiency: Improves system SEER ratings by modulating refrigerant flow based on real-time load requirements.
Common Questions & Technical Support
Is this TXV compatible with older R22 systems?
No, the Nordyne 664350 is specifically designed for R410A refrigerant pressures and flow characteristics. Using this valve with R22 will lead to erratic system behavior and potential compressor failure.
What are the symptoms of a failing Nordyne expansion valve?
Common indicators include localized frost on the inlet, high discharge pressure combined with low suction pressure, or a hunting compressor where the superheat fluctuates wildly.
Does this valve include the sensing bulb?
Yes, this refrigerant metering device includes the integrated sensing bulb required for thermal feedback from the suction line to modulate the internal needle valve.
