Hussmann 3031930 Expansion Valve Edge 1/3 Ton

Product Description

The HUSSMANN 3031930 is an expansion valve designed for use in commercial refrigeration systems. Expansion valves regulate refrigerant flow into the evaporator coil, maintaining proper superheat and system efficiency. This part is identified as an Edge-type unit sized for 1/3-ton capacity applications. It is typically installed by a licensed HVAC-R technician or refrigeration mechanic as part of a service or system retrofit procedure.

This expansion valve is suited for commercial refrigeration equipment. The Edge designation and 1/3-ton sizing indicate it is matched to smaller-capacity evaporator circuits commonly found in commercial display cases, reach-in coolers, or similar low-load refrigeration systems. Consult the equipment's service documentation to confirm proper valve selection before installation.
