A Traulsen 325-60080-42 Expansion Valve/TXV meters refrigerant flow to sustain accurate cooling control and stable performance in the system.
The expansion valve/TXV regulates refrigerant flow into the evaporator so the blast chiller can maintain proper low-temperature cooling and efficient heat exchange. Its design for R-404A low-temperature applications matters because accurate metering supports stable pressure control, protects system components and promotes consistent performance under demanding operating conditions.
The expansion valve/TXV may be wearing out if the blast chiller shows inconsistent cooling, longer pull-down times, temperature fluctuations or poor evaporator performance. Physical signs can include frost buildup in abnormal areas, visible refrigerant leaks, corrosion around connections or unusual hissing and environmental signs may include higher ambient stress causing erratic refrigerant control.
