Danfoss NRV 22s Check Valve 1 1/8 in ODF Angleway 020-1060
Danfoss · HVAC & Refrigeration · Check Valves
Danfoss NRV 22s piston-type check valve (non-return valve), OEM P/N 020-1060. Controls unidirectional refrigerant flow to prevent back-flow in commercial refrigeration and air-conditioning systems. The NRV opens at a low minimum pressure differential (0.04 bar / 0.58 psi). Angleway pattern, Solder, ODF connection 1 1/8 in, inlet and outlet. Built-in damping piston. Max working pressure 46 bar (667 psig); media temperature -50 to 140 °C (-58 to 285 °F). Kv per the NRV/NRVH datasheet. UL (C UL US Listed) and EAC. Refrigerant compatibility per the NRV/NRVH datasheet — verify against your system charge. Price on quote.

Compatibility
Install in the direction of the flow arrow. The differential pressure across the valve must exceed the minimum opening pressure differential (0.04 bar), including at the lowest capacity of capacity-regulated compressors. Braze the ODF solder ends with care to protect the internal seals. Verify code, connection size and spring variant (NRV vs NRVH) before ordering.
