Africa’s water security challenge is reshaping the continent’s infrastructure priorities. Countries such as Egypt, Morocco, and South Africa are investing billions in desalination, wastewater treatment, and water recycling to meet industrial and municipal demand. Egypt alone plans to increase its desalination capacity from 1.3 million m³/day in 2023 to 8.8 million m³/day by 2050, driven by over 20 mega projects.
These projects are fueling demand for reliable, corrosion-resistant industrial valves that can perform under high salinity and variable pressure conditions. Long lifecycle and minimal downtime are essential for national resilience.
Q1: Why is demand for desalination valves increasing in Africa?
A1: Rapid infrastructure expansion and water scarcity have made desalination a national priority.
Q2: Which countries are leading the trend?
A2: Egypt, Morocco, and South Africa lead in large-scale PPP and funded water projects.

“The future of Africa’s water security depends on the reliability of each component within its infrastructure—valves included.”
Seawater desalination and wastewater reuse create harsh, corrosive environments that demand specialized materials. Standard carbon steel valves often fail under chloride exposure, leading to leaks and costly maintenance. Dingliu’s duplex stainless steel, rubber-lined, and PTFE-lined valves prevent corrosion and ensure long-term sealing reliability.
Q1: What causes corrosion in desalination valves?
A1: High chloride content and sediment in seawater accelerate corrosion on unprotected metals.
Q2: How can maintenance costs be reduced?
A2: Using corrosion-proof materials and easy-service designs extends intervals between maintenance cycles.
