Danfoss check valves ensure proper flow direction and prevent refrigerant from condensing due to backflow from the warmer part of the system to the colder evaporator. They can be used in liquid, suction, and hot gas pipelines in refrigeration and air conditioning systems with refrigerants from groups HCFC, HFC, flammable HC, and NH3. Special versions with a maximum operating pressure of 90 bar are available for CO2 installations. Valves are available in straight-through and angled versions.

Check valves applications:
The check valve eliminates the problem of resonance during partial thermal load of the refrigeration system. It prevents refrigerant backflow and condensation in the colder part of the system, ensuring proper flow direction.
NRV and NRVH valves optimized for applications in refrigeration and air conditioning systems filled with fluorinated refrigerants, in liquid, suction, and hot gas pipelines. The NRV series is available with solder or threaded connections and with oversized solder connections, providing flexibility in valve usage. The NRVH valve is designed for systems with compressors connected in parallel.
CHV-X valves are available in angled versions. They open at very low pressure differentials, ensuring favorable flow conditions and allowing for easy dismantling for inspection and servicing. CHV-X SS check valves made of stainless steel are available in angled and straight-through versions.
Check valves with a built-in shut-off function, available in angled versions. SCA-X SS valves are made of stainless steel.
