Hoshizaki 4a5302-01 Expansion Valve Commercial Refrigeration

Product Description

The HOSHIZAKI 4a5302-01 is a thermostatic expansion valve (TXV) designed for use in commercial refrigeration and ice machine systems. The TXV meters refrigerant flow into the evaporator based on superheat, maintaining efficient heat transfer and protecting the compressor from liquid slugging. This component is a direct OEM replacement part sourced from HOSHIZAKI, ensuring correct fit and function within the refrigerant circuit. Installation is performed by licensed HVAC-R technicians with experience in commercial refrigeration systems.

This expansion valve is used in commercial refrigeration applications typical of HOSHIZAKI equipment, including ice machines and reach-in refrigeration units found in foodservice and commercial kitchen environments. The valve manages refrigerant metering at the evaporator inlet, which is critical for maintaining proper system capacity and energy efficiency. It is suited for replacement during routine refrigerant circuit servicing or when diagnosing issues related to improper superheat, icing, or insufficient cooling capacity.

Installation Notes

Installation of expansion valves requires an EPA Section 608 certified HVAC-R technician and proper refrigerant recovery equipment. Always recover and reclaim system refrigerant before opening the refrigerant circuit, following applicable federal and local environmental regulations. The system must be fully evacuated and pressure-tested after valve replacement before recharging with refrigerant. Refer to the equipment service manual for system-specific procedures and refrigerant type requirements.
