Hoshizaki 447283-04 Ice Machine Expansion Valve

The Hoshizaki 447283-04 Expansion Valve is an essential accessory in refrigeration equipment, especially in ice makers. It regulates the flow of the refrigerant to allow heat exchange and form the better ice texture. The valve works by decreasing the pressure of the refrigerant while passing from the state of a high-pressure liquid and becoming low-pressure vapor that are essential for cooling. It has a diaphragm and sensing bulb to make changes in the refrigerant flow dependent on the temperature, hence stabilizing the evaporator temperature. The advantages of this expansion valve include increased energy efficiency and cooling performance, and longer life of refrigeration systems through controlling excessive refrigerant.
