Danfoss 020-1042 Check Valve
The Danfoss 020-1042 is a high-performance NRV 12 check valve designed for integration into commercial refrigeration and air conditioning systems. Engineered for durability and precision, this 1/2" flare check valve ensures unidirectional flow and prevents back-condensation from warm system components to the evaporator. Featuring a built-in damping piston, the NRV 12 is ideal for installation in lines with high pulsation, such as compressor discharge lines, where it effectively stabilizes flow and reduces mechanical wear. With a maximum working pressure (MWP) of 46 bar (667 psig) and a low minimum pressure drop of 0.72 psi (0.05 bar), this valve provides optimal efficiency across a wide range of fluorinated refrigerants, including R410A, R404A, and R134a. This straightway refrigeration check valve is built with a robust brass body and a hermetic design to minimize potential leak paths, ensuring reliable performance in demanding contractor service and new installations.
Key Benefits for Technicians:- Enhanced Stability: The internal damping piston handles compressor discharge pulsations without premature failure.
- Versatile Compatibility: Rated for liquid, suction, and hot gas lines across various HVACR applications.
- Low Pressure Drop: Designed to maintain system capacity with a high Kv value of 2.05 m³/h.
- Reliable Sealing: Features a high-grade Teflon disk for tight closure and prevention of refrigerant backflow.
- Durable Construction: Brass body and flare connections ensure a secure, leak-resistant fit in the field.
Is the NRV 12 suitable for oil lines?
No, Danfoss NRV and NRVH series valves are not recommended for oil line applications; they are specifically designed for refrigerant vapor and liquid lines.
What is the minimum opening pressure for this valve?
The NRV 12 requires a minimum differential pressure of 0.72 psi (0.05 bar) to fully open, ensuring the piston moves to the stop face for unrestricted flow.
Can I use this valve in a parallel compressor rack?
While the NRV 12 is suitable for many discharge lines, for systems with high vibration or parallel compressors, consider the NRVH version which includes a stronger spring for improved resonance control.
