A Traulsen 325-60080-31 Thermo Ezpansion Valve meters refrigerant flow to maintain stable cooling performance within the system.
The thermo expansion valve regulates refrigerant flow into the evaporator so the blast chiller can maintain proper low-temperature cooling and stable operating efficiency. Its design for R-404A low-temperature applications matters because accurate metering supports consistent heat transfer, protects system balance and reduces strain on connected refrigeration components.
The thermo expansion valve may be nearing replacement if the blast chiller shows inconsistent cooling, longer pull-down times or unstable evaporator performance during low-temperature operation. Physical signs can include refrigerant leaks, corrosion or frost buildup around the valve body and you might notice environmental conditions such as vibration, contamination or moisture exposure that could accelerate wear.
