Kolpak 10828a Expansion Valve AAE2SW85-GT-5827-4

Product Description

The KOLPAK 10828a is a commercial refrigeration expansion valve kit designed to regulate refrigerant flow into the evaporator coil of a walk-in cooler or freezer system. Expansion valves meter refrigerant based on suction-line superheat, maintaining the correct refrigerant state entering the evaporator and protecting the compressor from liquid slugging. This kit is identified by valve assembly code AAE2SW85-GT-5827-4 and is sourced directly from KOLPAK as a genuine OEM replacement part. Licensed refrigeration technicians and commercial HVAC-R service professionals handle this component during system service or repair.

This expansion valve kit is intended for use in KOLPAK commercial refrigeration equipment, including walk-in coolers and walk-in freezers where the AAE2SW85-GT-5827-4 valve assembly is the specified component. It is suited for commercial food-service environments where consistent refrigerant metering is critical to maintaining proper cabinet temperatures and system efficiency. Consult the unit nameplate and service documentation to confirm correct valve sizing before installation.

Compatibility

Designed as a genuine OEM-style replacement expansion valve for KOLPAK commercial walk-in refrigeration units specifying valve assembly AAE2SW85-GT-5827-4. Verify against the equipment model number and service manual before ordering.

Installation Notes

Expansion valve replacement must be performed by a licensed HVAC-R technician holding an EPA Section 608 certification, as the work involves recovering and recharging refrigerant. Recover all refrigerant from the system and verify the system is de-energized before removing the existing valve. Follow the equipment manufacturer's service documentation for proper valve orientation, sensing bulb placement, and equalization line connection. Leak-check all joints with an electronic refrigerant detector after recharging the system.
