Danfoss NRV 35s Check Valve | 1 3/8 in (35 mm) ODF Solder | 46 bar

Product Description:

The Danfoss NRV 35s (020-1061) is engineered for the high-capacity demands of the UAE‘s industrial cooling infrastructure. Serving as a unidirectional guard for large-diameter pipelines, it prevents the back-condensation of refrigerant and protects compressors during system standby in Dubai’s extreme heat. Featuring 1 3/8 in (35 mm) ODF solder connections, this valve ensures a permanent, high-strength brazed joint capable of withstanding the intense vibrations of heavy-duty UAE mechanical rooms. With a robust 46 bar maximum working pressure and an exceptional Kv value of 19.0 $m^3/h$, it delivers high-volume flow with minimal resistance, making it the preferred choice for large chillers and district cooling projects across the UAE.

Key Features & Benefits:

• Ultra-High Flow Capacity: 1 3/8 inch ports provide massive flow rates (Kv 19.0 $m^3/h$), essential for energy efficiency in large UAE installations.
• Heavy-Duty Hermetic Seal: ODF solder ports offer a permanent, leak-proof connection that is vital for long-term reliability in the UAE.
• Resonance-Free Operation: Specially designed internal mechanism prevents pulsation and vibration in high-velocity lines across the UAE.
• Broad Temperature Range: Reliable performance from -50°C to +140°C, suitable for high-temperature discharge gas in Dubai.
• Corrosion Resistance: Built with high-grade materials to survive the humid and saline air conditions of coastal UAE sites.

FAQs:

• Q: Where is the NRV 35s (020-1061) typically installed in UAE plants?
• A: It is most commonly found in the discharge or liquid lines of large-scale chillers and industrial cooling systems throughout the UAE.
• Q: Does this valve handle high-pressure refrigerants like R410A in Dubai?
• A: Yes, its 46-bar rating and industrial-grade internals are fully optimized for the high-pressure HFCs used in UAE projects.
• Q: Why is the Kv value of 19.0 $m^3/h$ important for UAE cooling?
• A: A higher Kv value means less pressure drop across the valve, which directly translates to lower energy consumption for large UAE cooling systems.
