Victory 303-228D Txv Expansion Valve 1/4 X 3/8 Odf

Product Description

The VICTORY 303-228D is a thermostatic expansion valve (TXV) designed for use in commercial refrigeration 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 features ODF connections sized at 1/4 inch inlet and 3/8 inch outlet, and is compatible with R404A refrigerant. It is typically installed by a licensed refrigeration technician or HVAC-R service professional during new equipment installation or component replacement service calls.

This TXV is suited for commercial refrigeration applications, including walk-in coolers, reach-in cases, and similar low-temperature or medium-temperature refrigeration equipment. The EFV-1/5-C designation indicates a specific capacity rating and valve body configuration for targeted system fitment. Proper sizing of a TXV to the evaporator load is critical for stable superheat control and overall system performance.

Key Features

• ODF connection sizing: 1/4 inch inlet x 3/8 inch outlet for direct solder connections
• Compatible with R404A refrigerant, a common medium in commercial refrigeration systems
• EFV-1/5-C valve body configuration for precise capacity-matched refrigerant metering
• OEM-style replacement component for VICTORY commercial refrigeration equipment
• Designed for stable superheat control to protect the compressor from liquid refrigerant slugging

Compatibility

Designed as an OEM-style replacement TXV for VICTORY commercial refrigeration equipment. No specific model compatibility data was provided in the input; consult the equipment service manual or VICTORY parts documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed HVAC-R technician holding the appropriate EPA Section 608 certification for refrigerant handling. The system must be recovered and the refrigerant charge removed before removing the existing valve. ODF fittings require proper brazing technique with nitrogen purge to prevent oxidation inside the refrigerant circuit. After installation, the system should be leak-checked, evacuated, and recharged to the equipment manufacturer's specified charge weight before startup.
