Westinghouse 669690R Txv Assembly R-22 2 Ton Ac Indoor Coil

Product Description

The WESTINGHOUSE 669690R is a thermostatic expansion valve (TXV) assembly designed for use in air conditioner indoor coil applications. The TXV meters refrigerant flow into the evaporator coil based on suction line superheat, maintaining efficient heat transfer across the coil surface. This assembly is rated for R-22 refrigerant service at 2 tons of cooling capacity. It is a direct OEM-style replacement part installed by licensed HVAC technicians during routine maintenance, refrigerant system repairs, or evaporator coil service calls where the original valve has failed or lost regulation.

This TXV assembly is used in residential split-system air conditioning applications where the indoor coil is a standalone evaporator unit. The 669690R is specified for indoor coil models within the C6BA-T and C6BH-T series, including part numbers C6BA-T24C-B, C6BH-T24C-A, and C6BH-T24C-B. Technicians servicing these coil assemblies should confirm the coil model and refrigerant type before ordering to ensure correct valve sizing and sensing bulb compatibility.

Key Features

• OEM-replacement TXV assembly for C6BA-T and C6BH-T series indoor coils
• Rated for R-22 refrigerant systems at 2-ton capacity
• Regulates refrigerant flow based on suction superheat for consistent coil performance
• Direct fitment to specified indoor coil part numbers without modification
• Designed for residential split-system evaporator coil applications

Compatibility

Specified for use on WESTINGHOUSE air conditioner indoor coil models C6BA-T24C-B, C6BH-T24C-A, and C6BH-T24C-B within the C6BA-T and C6BH-T series.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. The refrigerant system must be recovered and the system fully de-pressurized before removing the existing TXV. After installation, the system should be evacuated to the required micron level before recharging with R-22 refrigerant. Confirm the sensing bulb is properly secured to the suction line and insulated to ensure accurate superheat sensing.
