Nordyne 669845R TXV Valve
The Nordyne 669845R TXV Valve is a precision-engineered thermal expansion valve designed specifically for R410A refrigerant applications in residential and light commercial systems. Engineered as a genuine Nordyne OEM part, this hard shutoff TXV regulates refrigerant flow into the evaporator coil with high accuracy, stabilizing superheat and maximizing the energy efficiency of the cooling cycle. Because it is a non-bleed port valve, it maintains a positive seal when the compressor cycles off, preventing refrigerant migration and ensuring rapid cooling upon startup.
For contractors performing maintenance or upgrades on Nordyne furnace coils or air handlers, the 669845R provides a reliable metering solution that prevents liquid slugging and evaporator freeze-ups. This R-410A metering device features a bronze body construction for high-pressure durability and a remote sensing bulb for responsive temperature modulation. When installing this OEM HVAC component on single-phase systems with a reciprocating compressor, verify if a hard start kit is required due to the unequalized pressures inherent in hard shutoff designs.
Key Benefits:- Optimized Performance: Maintains precise refrigerant flow control to achieve optimal SEER ratings and heat transfer efficiency.
- OEM Compatibility: Direct-fit replacement TXV for Nordyne, Intertherm, and Miller HVAC units, ensuring matching performance curves.
- System Protection: Internal check valve functionality protects the compressor by preventing backflow in heat pump applications.
- R410A Ready: Factory-calibrated specifically for high-pressure R-410A systems to ensure accurate superheat settings right out of the box.
- How do I ensure a proper seal during installation? Use a backup wrench on the distributor hex nut to prevent torque damage to the copper tubing and ensure the Teflon ring seal is seated squarely.
- Does this valve require a start capacitor? As a hard shutoff TXV, it does not equalize pressures on shutdown. If your system uses a single-phase reciprocating compressor, a hard start kit may be necessary for reliable ignition.
- Where should the sensing bulb be mounted? Secure the bulb to a horizontal section of the suction line near the evaporator outlet, ensuring the entire length of the bulb makes firm contact with the copper before insulating.
