Client: Major Municipal Water Authority, EMEA Region
Challenge: The client required robust and corrosion-resistant valves for their new desalination plant's raw seawater intake and brine discharge lines. The high salinity and abrasive nature of the media, combined with large flow volumes, necessitated valves with exceptional durability and precise flow modulation. Previous valves from other suppliers showed premature wear and leakage, leading to costly downtime.
Solution: We supplied twenty-five units of the 75/90-42-235-632, custom-engineered with a duplex stainless steel body (ASTM A890 Gr. 4A CD3MN) and a ceramic-coated disc for enhanced abrasion resistance. These valves were integrated with intelligent electric actuators for remote monitoring and precise control.
Results: After three years of continuous operation, all valves have performed flawlessly, demonstrating zero visible corrosion or significant wear. The precise flow control has optimized the plant's reverse osmosis process, leading to a 7% reduction in energy consumption for pumping, surpassing the client's energy-saving targets. The client reported significant savings in maintenance costs and increased operational uptime. "The reliability of these valves has been a game-changer for our plant's efficiency," stated the plant manager.
