Description
The Nordyne 669565R is an OEM thermostatic expansion valve (TXV) engineered specifically for R410A refrigerant systems rated at 2.5 tons. Designed as a direct factory replacement, this valve delivers precise refrigerant metering to the evaporator coil, helping maintain optimal system efficiency, consistent cooling performance, and reliable operation across a wide range of load conditions.
Key Features
- OEM Nordyne replacement TXV for accurate, drop-in fitment
- Designed for R410A refrigerant — compatible with modern, environmentally preferred systems
- 2.5-ton (30,000 BTU/hr) capacity rating for residential and light-commercial applications
- Includes external equalizer line for accurate superheat sensing and control across longer evaporator circuits
- Thermostatic sensing bulb precisely regulates refrigerant flow in response to evaporator outlet conditions
- Helps prevent evaporator flooding and compressor slugging by maintaining proper superheat
- Supports system efficiency and longevity by optimizing refrigerant charge distribution
Application
The 669565R is a factory-authorized replacement part intended for use in Nordyne-branded HVAC equipment, including units sold under the Frigidaire, Tappan, Gibson, Westinghouse, and related brand families. Always verify compatibility with the specific equipment model before installation.
Why TXV with External Equalizer?
An external equalizer port allows the valve’s sensing element to reference actual evaporator outlet pressure rather than inlet pressure. This is especially important in multi-circuit or longer evaporator coils where pressure drop across the coil is significant, ensuring accurate superheat control and protecting the compressor from liquid refrigerant slugging.
