Danfoss WVFX 25 High Pressure Water Valve | 1 in | 4.0 – 23.0 bar

Product Description:

The Danfoss WVFX 25 (003N4105) is a robust solution for managing water-cooled condensers in the demanding UAE environment. With 1 in (G 1) threaded connections and a flow capacity of 5.5 $m^3/h$, it effectively bridges the gap between small commercial units and large industrial plants. This model is specifically designed for high-pressure applications, allowing adjustments up to 23.0 bar, which is essential for stable operation with modern refrigerants under high ambient temperatures in Dubai. By modulating water flow in direct response to refrigerant pressure, it prevents water wastage and ensures the refrigeration cycle remains efficient, protecting the compressor from the strain of fluctuating head pressures common in the Middle East.

Key Features & Benefits:

• High-Pressure Versatility: Regulating range of 4.0 to 23.0 bar makes it ideal for high-pressure HFC systems throughout the UAE.
• Precise Modulation: Automatically adjusts water flow to keep condensing pressure constant, ensuring reliable cooling in Dubai.
• Optimized Capacity: Flow rate of 5.5 $m^3/h$ is perfectly sized for mid-range water-cooled chillers in UAE commercial buildings.
• Sustainability Focused: Directly reduces water consumption and pumping costs, helping UAE businesses achieve green building certifications.
• Durable Design: Built with high-quality bellows and a cast iron body to ensure a long service life in UAE industrial settings.

FAQs:

• Q: When should I choose the WVFX 25 (003N4105) over the WVFX 20 in the UAE?
• A: Choose the WVFX 25 when your system requires a higher water flow rate (5.5 $m^3/h$) or uses 1″ piping, common in medium-sized UAE process cooling applications.
• Q: Can this valve handle poor water quality in Dubai?
• A: While robust, it is always recommended to use filtered water in UAE systems to prevent debris from affecting the valve’s seating and modulation accuracy.
• Q: Is the 23 bar limit enough for all refrigerants in the UAE?
• A: It covers most common HFCs. However, for extreme high-pressure R410A scenarios in very high ambient Dubai heat, always check your peak condensing pressure against the 26.5 bar max limit.
