Duplex Steel Surge Anticipation Valve are specially engineered to protect pipelines and pumping systems from pressure surges and water hammer during sudden pump trips or power failures. By anticipating the surge and automatically opening to relieve excess pressure, they safeguard critical infrastructure in desalination plants, power stations, water transmission lines, and industrial cooling systems. Duplex Steel Surge Anticipation Valve For Desalination Plants.
The use of Duplex Stainless Steel provides exceptional resistance against chloride-induced stress corrosion cracking, seawater corrosion, and erosion, making these valves ideal for offshore, desalination, and other aggressive environments.
