Description
Danfoss 067L6004 Thermostatic Expansion Valve (TXV) R454B is a refrigerant component used to regulate liquid refrigerant flow into the evaporator based on superheat condition. In HVAC systems it operate as a metering element that balances refrigerant supply with cooling need, ensuring stable evaporator performance, and compressor protection. It features an orifice size of 7, and is rated for approximately 6 TR capacity making it suitable for medium-capacity applications. It responds to suction line temperature changes to maintain precise superheat control helping prevent refrigerant flood-back, improve efficiency, and support consistent system operation under load conditions.
