Trane VAL07574 Expansion Valve 2.5 Ton

Product Description

The TRANE VAL07574 is a thermostatic expansion valve (TXV) rated for 2.5-ton cooling capacity, designed for use in residential and light-commercial refrigerant systems. It regulates refrigerant flow into the evaporator coil, maintaining proper superheat and protecting the compressor from liquid slugging. The inlet connection measures 0.31 inches ODF and the outlet connection measures 0.63 inches ODF. Licensed HVAC technicians install this valve as part of routine system repairs or performance restoration on split-system and package unit air conditioners.

This expansion valve fits within refrigerant circuit assemblies where precise metering of liquid refrigerant is required. It is suited for 2.5-ton split-system cooling equipment operating with compatible refrigerants. Typical installation scenarios include evaporator coil replacements, refrigerant system overhauls, and TXV conversions from fixed-orifice metering devices. Consult equipment documentation to confirm refrigerant type and system design before installation.

Key Features

• 2.5-ton capacity rating for accurate refrigerant metering in residential and light-commercial systems
• 0.31-inch ODF inlet connection for compatibility with standard liquid-line tubing
• 0.63-inch ODF outlet connection sized for suction-side evaporator coil entry
• Functions as a direct OEM-style replacement, maintaining system efficiency and superheat control
• Supports proper evaporator performance and compressor protection against liquid refrigerant slugging

Compatibility

Designed as an OEM-style replacement expansion valve for TRANE 2.5-ton refrigerant systems with 0.31-inch ODF inlet and 0.63-inch ODF outlet connections. Verify system refrigerant type, tonnage, and connection sizing against equipment documentation before ordering.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant and de-energize the system before removing the existing valve. Use proper brazing techniques and nitrogen purge when making ODF connections to prevent oxidation inside the refrigerant circuit. After installation, leak-test all joints and verify system superheat and subcooling readings before returning the equipment to service.
