AAON Thermal Expansion Valves (TXVs / TEVs)

AAON Thermal Expansion Valves (TXVs / TEVs) regulate the flow of refrigerant into the evaporator coil by sensing superheat, ensuring that the evaporator operates at peak efficiency. These valves adjust automatically as load conditions change, maintaining stable cooling performance and preventing liquid floodback to the compressor. By installing Aaon TXVs, technicians optimize refrigerant distribution, improve system reliability, and help maintain consistent indoor temperatures, especially in varying humidity conditions.
