Danfoss NRV 6S check valve — 1/4 in ODM x ODF solder, straightway, 49 bar, code

Danfoss NRV 6s check (non-return) valve, code 020B1182 — a spring-loaded straightway check valve from the Danfoss NRV range for commercial A/C and refrigeration, preventing reverse (backward) refrigerant flow. This SKU has a mixed solder connection: 1/4 in ODM (male, outside-diameter) solder inlet and 1/4 in ODF (female) solder outlet, which lets the valve butt directly into a line without an extra coupling. minimum opening pressure 0.04 bar; maximum working pressure 49 bar (710 psig); media temperature range -50 to 155 C (-58 to 311 F). Suitable for HCFC/HFC/HFO and hydrocarbon refrigerants. UL listed (C UL US) and EAC. Price on quote.
