Thermostatic expansion valves

Precise operation and long service life

In the Danfoss range of thermostatic expansion valves you can find the product to match your needs, no matter what refrigeration solution you are looking for. The valves are optimized for a variety of refrigerants and operating ranges with fixed or adjustable superheat settings and many connection options.

With Danfoss thermostatic expansion valves, you can expect precise operation and long service life of your refrigeration system. The valves control the injection of liquid refrigerant into evaporators and protect the compressor motor against liquid refrigerant. 

The thermostatic expansion valve allows you to keep a constant superheat (or refrigerant level) at varying load situations in the refrigeration system to save energy.
