Danfoss WVH 50 Water Regulating Valve Body | 2 in Flange | 016D5050
Product Description: The WVH 50 (016D5050) is a pressure-operated water regulating valve body engineered for systems where reliability is non-negotiable. In the UAE’s demanding cooling sector—including district cooling and large-scale industrial manufacturing—the WVH series stands out for its ability to handle higher working pressures compared to the standard WVFM or WVS ranges. This 2-inch flanged valve body serves as the robust foundation of the assembly; it modulates water flow based on the refrigerant’s condensing pressure (via a pilot). By ensuring the compressor operates at a constant head pressure even during the peak of the Dubai summer, this valve maximizes system efficiency and significantly reduces water consumption.
Key Features & Benefits:
- High-Pressure Capability: Specifically designed for systems that exceed the pressure limits of standard water valves, making it ideal for modern UAE industrial chillers.
- Proportional Regulation: Provides smooth, infinite modulation of water flow, preventing pressure surges and “water hammer” in large piping networks.
- Large 2-Inch Capacity: The DN 50 size offers high flow rates ($K_v$ value) to support large-capacity condensers common in Middle Eastern plant rooms.
- Corrosion Resistance: Built with high-grade materials to withstand the treated and sometimes aggressive cooling water used in the Emirates.
- Replaceable Internal Parts: The modular design allows for internal components to be serviced or replaced without removing the entire valve body from the line, minimizing downtime.

FAQs:
- Q: What is the difference between WVH and WVS valves in the UAE?
- A: WVH valves (like 016D5050) are generally rated for higher operating pressures and are built for more intensive industrial applications than the WVS series.
- Q: Does this include the pilot valve and bellows?
- A: This code (016D5050) is typically the valve body. The pilot assembly and pressure bellows are often specified separately depending on the required pressure range.
- Q: Can this be used for sea-water cooling in Abu Dhabi?
- A: Standard WVH valves are for fresh water or neutral brines. For sea-water applications, specialized corrosion-resistant versions or materials would be required.
