Danfoss NRV 10s Check Valve 10 mm ODF Solder Straightway 020B1015
Danfoss · HVAC & Refrigeration · Check Valves
Danfoss NRV 10s piston-type check valve (non-return valve), OEM P/N 020B1015. Controls unidirectional refrigerant flow to prevent back-flow in commercial refrigeration and air-conditioning systems. Straightway pattern, Solder, ODF, 10 mm, inlet and outlet. Built-in damping piston suits lines subject to pulsation, such as the compressor discharge line. Max working pressure 49 bar (710 psig); media temperature -50 °C to 155 °C. NRV = standard spring; the stronger-spring NRVH variant is the counterpart for parallel-compressor duty. Refrigerant compatibility is listed on the datasheet — verify against your system charge.

Compatibility
Install in the direction of the flow arrow. The differential pressure across the valve must exceed the minimum opening pressure differential, 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.
