Brand history, product range & what we stock
Danfoss was founded in 1933 in Denmark by engineer Mads Clausen with the invention of the thermostatic expansion valve — a component that remains at the core of refrigeration and air conditioning systems worldwide. Today, Danfoss A/S operates in 100+ countries and is a global leader in refrigeration controls, variable frequency drives, compressors, and HVAC electronic controls. The company's product portfolio spans thermostatic and electronic expansion valves, solenoid valves, pressure and temperature controls, frequency converters, and an extensive range of refrigerant flow control components.

Common questions about Danfoss OEM replacement parts
Danfoss expansion valves are available for a wide range of refrigerants including R-22, R-134a, R-404A, R-407C, R-410A, R-448A, R-449A, R-452A, and CO₂ (R-744). When selecting a TXV, specify the refrigerant type, capacity (tons or kW), and evaporator temperature range. Our search filters make it easy to narrow down the correct valve for your application.
The T2 series uses an internal equalizer and is suited for single-circuit evaporators with low pressure drop. The T5 series uses an external equalizer connection and is preferred for multi-circuit evaporators or applications with higher distributor pressure drops. Both are available in the same capacity range — selection depends on your specific evaporator configuration.
