Danfoss · HVAC & Refrigeration · Check Valves
Danfoss NRVA 65 check-valve body, OEM P/N 020-2026 — the flangeless valve housing (without flanges) of the NRVA industrial refrigeration check valve. Ordered separately from the weld/socket/solder/FPT flange set so the same body can be matched to any connection standard. Contains the damping piston and PTFE seat; prevents reverse refrigerant flow in ammonia (R717), HCFC and HFC plant. Straightway pattern, no orientation limitation. Max working pressure 40 bar (580 psig); media temperature -50 °C to 140 °C. Kv 75 m³/h. Pair with the matching NRVA flange kit for the required connection.
