Product details
Danfoss NRD 12s Differential Pressure Valve | 1/2 in ODF Solder | 46 bar
Product Description:
The Danfoss NRD 12s (020B1132) is an essential component for high-efficiency refrigeration plants in the UAE. Functioning as a differential pressure valve, it begins to open at a pressure drop of 1.4 bar and is fully open at 3 bar, effectively bypassing hot gas to the receiver to maintain operational stability. This model features 1/2 in ODF solder connections, providing a permanent and leak-proof installation suitable for the intense thermal cycles in Dubai. With a high maximum working pressure of 46 bar, it is perfectly compatible with modern high-pressure refrigerants like R410A and R32. Its durable construction ensures it can withstand the demanding industrial and commercial environments typical of the UAE‘s cooling infrastructure.
Key Features & Benefits:
- Stable Pressure Control: Ensures constant receiver pressure, which is vital for the reliable operation of expansion valves in UAE cooling systems.
- Optimized for High Pressure: 46-bar rating allows for seamless integration into the latest high-pressure refrigeration technology in Dubai.
- Leak-Proof Solder Joints: 1/2 in ODF connections provide a superior, permanent seal designed for the high-vibration environments of UAE plants.
- Energy Efficiency: Helps maintain optimal system balance, reducing the workload on compressors during the extreme UAE summer.
- Robust Industrial Build: Engineered to deliver long service life even in the humid and high-ambient conditions of the UAE.

FAQs:
- Q: Why is the NRD 12s (020B1132) important for UAE refrigeration?
- A: It prevents the receiver pressure from dropping too low during cooler nights in the UAE, ensuring that the system can always deliver liquid refrigerant to the evaporators.
- Q: Can this valve handle the high-pressure R410A systems in Dubai?
- A: Yes, its 46-bar maximum working pressure makes it fully compliant with high-pressure refrigerant standards in the UAE.
- Q: What is the benefit of the ODF solder connection in the UAE climate?
- A: It provides a permanent, brazed hermetic seal that is far more reliable than mechanical fittings under the extreme outdoor conditions of the UAE.
