Check Valve

Modern refrigeration systems are often powered by compressors in parallel. In some cases, the hot gas will be used for defrosting of evaporators or to heat water for domestic use and central heating. In such systems check valves are essential to securethe operation. If the refrigerant is supposed to flow through other circuits or to flow inone direction only, check valves are a necessity.The number of types available has been adapted over the years in line with the evolvingcontext of the refrigeration and A/C industry. Today Danfoss offers a solution for almostevery application.Besides the known types of NRV/H in sizes from 6 to 35 with solder connections and from 6 to 19 with flare connections, the NRVA is also available in sizes 15 to 65 as a straightway valve with various flange options.
