Danfoss NRV 16 Check Valve | 5/8 in Flare Connection | 46 bar

Product Description:

The Danfoss NRV 16 (020-1043) is an essential component for maintaining system efficiency and protecting compressors across the UAE. Featuring 5/8 in flare connections, this valve allows for quick and easy installation or replacement without the need for brazing, making it a favorite for service technicians in Dubai. It effectively prevents the back-flow of refrigerant from warm to cold system parts, which is critical during the high-temperature fluctuations of the UAE summer. With a maximum working pressure of 46 bar (667 psig), it is fully compatible with common HFC and HCFC refrigerants. Its robust construction ensures minimal pressure drop and quiet, resonance-free operation in both liquid and hot gas lines within Middle Eastern cooling plants.

Key Features & Benefits:

  • Easy Flare Installation: 5/8 inch flare ports allow for fast, mechanical connections, reducing downtime during UAE maintenance calls.
  • Reliable Backflow Prevention: Guards against refrigerant siphoning, ensuring optimal evaporator performance in UAE commercial units.
  • High Pressure Resilience: Rated for 46 bar, providing ample safety and compatibility for standard refrigeration systems in Dubai.
  • Versatile Application: Suitable for use in liquid, suction, and hot gas lines, offering flexibility for UAE HVAC designers.
  • Durable Design: Engineered to operate reliably in the high ambient temperatures and humid conditions of the UAE.
