Westinghouse 669564R Txv R-410A 2 Ton Indoor Ac

Product Description

The WESTINGHOUSE 669564R is an indoor thermostatic expansion valve (TXV) designed for residential and light-commercial air conditioning systems. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to optimize system efficiency and protect the compressor. This unit is rated for R-410A refrigerant at a 2-ton capacity. It also includes an equalized check valve, which allows the system to pressure-equalize on shutdown — a feature that simplifies compressor restart and reduces wear on starting components. Licensed HVAC technicians handle installation as part of a refrigerant-side repair or coil replacement.

This TXV is intended for indoor installation, mounted at or near the evaporator coil inlet. It is suited for split-system air conditioner applications using R-410A refrigerant in the 2-ton capacity range. The integrated equalized check valve adds functionality without requiring a separate check valve component in the liquid line, making it appropriate for systems where pressure equalization is needed across the metering device. Installation typically occurs during evaporator coil service, TXV replacement for loss of charge control, or system refrigerant conversion work.

Key Features

• Rated for R-410A refrigerant at 2-ton capacity
• Indoor thermostatic expansion valve for evaporator coil metering
• Integrated equalized check valve for pressure equalization on system shutdown
• Direct replacement TXV valve for air conditioner relay systems

Compatibility

Designed as an OEM-style replacement indoor TXV for R-410A air conditioning systems rated at 2 tons. The input data references use on air conditioner relay equipment. No additional specific model numbers or system families were provided in the product data.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Recover all refrigerant from the system before opening the refrigerant circuit — never vent refrigerant to atmosphere. Ensure the system is fully de-pressurized and the electrical disconnect is open before beginning work. Follow the equipment manufacturer's service instructions and applicable local mechanical codes when brazing, flaring, or connecting refrigerant-side components.
