Product details
Danfoss NRV 10 Check Valve | 3/8 in Flare Connection | 46 bar | 020-1041
Product Description:
The Danfoss NRV 10 (020-1041) is a fundamental component for maintaining system efficiency across the UAE. Equipped with 3/8 in flare connections, it allows for quick, mechanical installation and replacement without the need for brazing—a significant advantage for maintenance teams working in Dubai’s high-rise buildings and commercial facilities. This valve effectively prevents the back-flow of refrigerant from warm system sections to the evaporator, protecting the compressor and ensuring stable cooling during the intense UAE summer. With a maximum working pressure of 46 bar, it is a robust and reliable choice for both liquid and hot gas lines in a wide variety of Middle Eastern cooling applications.
Key Features & Benefits:
- Tool-Free Installation: 3/8 inch flare ports facilitate easy, screw-on connections, ideal for rapid field servicing in the UAE.
- Unidirectional Precision: Blocks refrigerant siphoning to prevent compressor damage and energy loss in UAE units.
- Resonant-Free Design: Engineered for quiet operation, making it suitable for noise-sensitive UAE environments like hotels and offices.
- Broad Temperature Tolerance: Rated to handle media from -50°C to +140°C, perfect for the wide operating ranges of UAE HVAC systems.
- High-Pressure Reliability: 46-bar rating ensures compatibility with standard HFC and HCFC refrigerants used throughout Dubai.
