Product details
Danfoss NRV 16s Check Valve | 5/8 in (16 mm) ODF Solder | 49 bar
Product Description:
The Danfoss NRV 16s (020B1018) is a professional-grade solution for preventing refrigerant back-condensation and protecting compressors in the demanding UAE environment. Designed for high-performance HVAC/R units, it ensures that refrigerant only moves in the intended direction, which is critical for system stability during Dubai’s extreme ambient heat. This model features 5/8 in (16 mm) ODF solder connections, providing a robust, permanent brazed joint that is highly resistant to vibration and thermal stress. With a maximum working pressure of 49 bar (711 psig), it is fully optimized for modern high-pressure refrigerants like R410A and R32, ensuring minimal pressure drop and long-term reliability in Middle Eastern installations.
Key Features & Benefits:
- Unidirectional Security: Effectively prevents back-siphoning of refrigerant, safeguarding compressors in UAE industrial units.
- Premium 49-bar Rating: Offers a superior safety margin for high-pressure refrigeration and air conditioning projects in Dubai.
- Leak-Proof Solder Design: 5/8 inch ODF connections provide a permanent, hermetic seal ideal for high-vibration UAE plant rooms.
- High Temperature Resilience: Rated for media temperatures up to +140°C, making it perfect for hot gas and discharge lines in the UAE.
- High Flow Capacity: Delivers a Kv value of 2.4 $m^3/h$, ensuring efficient system operation with minimal energy loss in UAE projects.

FAQs:
- Q: Why use the 5/8″ NRV 16s (020B1018) in UAE commercial systems?
- A: It provides a larger flow capacity than the NRV 12s, making it suitable for the higher cooling loads required in large UAE buildings.
- Q: Can this valve be used with CO2 systems in Dubai?
- A: While it has a high pressure rating of 49 bar, always check specific CO2 system requirements; it is primarily designed for high-pressure HFCs like R410A in the UAE.
- Q: Is the ODF solder connection better for coastal UAE areas?
- A: Yes, brazed joints are more resistant to the corrosive, humid air of Dubai and Abu Dhabi compared to mechanical flare fittings.
