Copeland 64103 Thermal Expansion Valve 5 Ton Aace-series

Product Description

The COPELAND 64103 is a thermal expansion valve (TXV) designed for use in refrigerant systems requiring precise flow control. The 64103 features an integrated check valve that prevents backflow, maintains proper refrigerant direction, and adds a layer of compressor protection. Sized for 5-ton capacity systems and configured with 3/8-inch and 1/2-inch connections, this valve meters refrigerant into the evaporator coil to match the load demand of the system. It is installed by licensed HVAC technicians during new equipment installation or compressor replacement service on AACE-Series equipment.

The COPELAND 64103 is suited for residential and light commercial air conditioning applications, including commercial refrigeration and industrial refrigeration systems where accurate refrigerant metering and backflow prevention are both required. Its compact and durable construction supports secure, reliable installation in tight equipment spaces typical of split-system and packaged HVAC equipment. The AACE-Series designation identifies the specific Copeland compressor family for which this valve is specified.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 refrigerant handling certification. Recover all system refrigerant and isolate the system before removing the existing valve. Ensure proper orientation of the valve body to maintain refrigerant flow direction as marked. Leak-test all connections before recharging the system and verify superheat settings after startup.
