General Electric 26Z72 Txv Valve 5 Ton R454B

Product Description

The GENERAL ELECTRIC 26Z72 is a thermostatic expansion valve (TXV) designed for use with R454B refrigerant in 5-ton cooling systems. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to protect the compressor and optimize system efficiency. This valve is a critical refrigerant-circuit component installed by licensed HVAC technicians during system commissioning, retrofit, or service work. At 1.15 pounds, it is a compact, purpose-built component matched to the pressure and flow characteristics of R454B, a lower-GWP refrigerant increasingly specified in modern residential and light-commercial equipment.

This valve is intended for 5-ton split or packaged systems charged with R454B refrigerant. It is suited for residential and light-commercial HVAC installations where equipment has been designed or updated to operate on R454B. Technicians replacing a failed TXV or retrofitting a coil assembly for R454B compatibility will find this valve appropriate for those applications. Always verify system tonnage and refrigerant type before ordering.

Key Features

• Rated for R454B refrigerant, a lower-GWP A2L alternative gaining adoption in new HVAC equipment
• Sized for 5-ton system capacity
• Lightweight at 1.15 pounds for straightforward handling during installation
• Meters refrigerant flow to maintain proper evaporator superheat
• OEM part from GENERAL ELECTRIC for reliable fitment in GE-compatible systems

Compatibility

Designed as an OEM-style TXV replacement for 5-ton HVAC systems operating on R454B refrigerant. No additional specific model compatibility data was provided in the product information.

Installation Notes

TXV valves must be installed by an EPA Section 608 certified HVAC technician. Recover all refrigerant and relieve system pressure before disconnecting any refrigerant-circuit components. Ensure the replacement valve is oriented correctly per the manufacturer orientation marking and that the sensing bulb is secured firmly to the suction line with proper thermal contact. Verify superheat settings after recharge to confirm correct valve operation.
