Nordyne 664344R Check Valve
The Nordyne 664344R is a high-performance R410A 3 Ton TXV Check Valve designed for precise refrigerant metering in residential and light commercial HVAC systems. This OEM Nordyne replacement part acts as a critical thermal expansion device, sensing evaporator temperature and pressure to regulate flow and maintain the ideal superheat. Engineered for 3-ton capacity units, the 664344R check valve ensures consistent cooling performance and prevents evaporator coil freeze-ups by adjusting refrigerant passage based on real-time load demands. Built with a durable bronze body, this HVAC expansion valve is a direct replacement for legacy part numbers 664344 and 664267, providing a reliable solution for technicians servicing air conditioners and heat pump systems.
Key Benefits:- Precise Refrigerant Control: Optimizes R410A refrigerant flow to maximize heat transfer efficiency and prevent liquid slugging in the compressor.
- OEM Compatibility: Specifically designed as an OEM Nordyne part to fit 3-ton evaporator coils and air handlers without modifications.
- Dual-Action Capability: Operates as both a metering device and a check valve, allowing for bi-directional flow in heat pump applications.
- Enhanced System Reliability: Maintains stable superheat levels, reducing mechanical stress on the cooling system components.
- Is the Nordyne 664344R compatible with R-22 systems? No, this thermal expansion valve is specifically calibrated for the pressure and temperature characteristics of R410A refrigerant.
- What tonnage is this TXV rated for? The Nordyne 664344R is designed for a 3-ton capacity cooling system.
- Does this valve replace the Nordyne 664344? Yes, the 664344R is the current technical replacement for part numbers 664344 and 664267.
