Valves and accessories

Danfoss's range of thermostatic expansion valves offers the perfect solution for your needs, no matter what refrigeration solution you're looking for. The valves are optimized for a variety of refrigerants and operating ranges, with fixed or adjustable superheat settings and numerous connection options.

‎ Danfoss thermostatic expansion valves ensure precise operation and a long service life for your refrigeration system. The valves control the injection of refrigerant into the evaporators and protect the compressor from any liquid backflow.

The thermostatic expansion valve allows you to maintain constant superheat (or refrigerant level) under variable load situations in the refrigeration system, in order to save energy.

Always available in stock Thermostatic expansion valves for R404A, R448, R449A, R452A, R134a, R407C.

Electronic thermostatic valves allow effective control of superheating, which depends on continuous adaptation of the expansion valve to changing operating conditions.

This operation can only be accomplished using the best available technologies that allow the refrigeration cycle to operate at maximum efficiency. For this reason, Omnia Frigo has recommended Danfoss.

‎ Danfoss Omnia Frigo software , it selects the electronic expansion valves best suited to the application being examined.

- Castel safety valves protect pressurized system parts. Omnia Frigo can handle requests for valves with specific customer pressure settings, identifying the appropriate product based on application data and the manufacturer's specifications.

Please specify the pressure, refrigerant nand conenction size so we can supply you the right safety valve.

‎‎‎‎ Vibration absorbers reduce the transmission of vibrations from the compressor to the pipes. Solutions are available for systems with HFC refrigerants and models suitable for R290. Select your model by specifically verifying the compatibility indicated by the manufacturer.

In addition to the refrigerant, the permissible pressure, pipe diameter and installation location must also be considered.

Omnia Frigo offers valves for hermetic compressors, valves for air conditioning and ball valves for shutting off the refrigeration circuit.

The choice varies according to the function of the tap, the refrigerant, the working pressure, the type of connection and the size of the pipes.

‎ Rotalock valves are used to create removable connections on refrigeration circuit components designed for this type of connection. To identify the correct fitting, you need to check the thread, size, type of seal, and connections of the components to be joined.

Components that look similar may have different application limits. Please inform our staff of the refrigerant, the required function, the operating pressures and temperatures, the connections, and, in case of replacement, the part number of the existing component.

We will help you identify the product to evaluate and verify its characteristics for your application.
