Nortek Global Hvac 904564 Txv Valve 4 Ton

Product Description

The NORTEK GLOBAL HVAC 904564 is a 4-ton thermostatic expansion valve (TXV) designed for use in split-system and packaged air conditioning and heat pump applications. The TXV regulates refrigerant flow into the evaporator coil by sensing suction line temperature and equalizing pressure, maintaining proper superheat across a range of operating conditions. This is an OEM-replacement component intended for installation by licensed HVAC technicians servicing residential and light-commercial cooling systems. The 904564 also cross-references as a replacement for part 669427, giving technicians flexibility when sourcing a verified OEM-equivalent valve.

This TXV is applicable to residential split-system and packaged cooling equipment operating under the Nordyne family of brands. Documented compatible brand lines include Frigidaire, Miller, Intertherm, Maytag, Revolve, and Gibson equipment built on Nordyne platforms. It is sized for 4-ton system capacity, making it a direct fit for mid-range residential and light-commercial cooling equipment in that tonnage range.

Key Features

• 4-ton rated capacity for mid-range residential and light-commercial cooling systems
• OEM-equivalent replacement ensuring factory-spec refrigerant flow and superheat control
• Cross-references part 669427 as an alternate or superseded part number
• Compatible across multiple Nordyne-platform brand lines for broad fitment
• Regulates evaporator refrigerant flow to maintain system efficiency under varying load conditions

Compatibility

Compatible with Frigidaire, Miller, Intertherm, Maytag, Revolve, and Gibson equipment built on Nordyne platforms. Also replaces part number 669427.

Installation Notes

TXV replacement must be performed by an EPA 608-certified HVAC technician, as the work involves recovering, evacuating, and recharging a sealed refrigerant system. Shut down and lock out the system and allow pressures to equalize before removing the existing valve. After installation, pull a deep vacuum on the system before recharging to manufacturer-specified refrigerant weight. Verify superheat and subcooling readings after startup to confirm correct valve operation.
