Safety Valve

Safety Valve

African Valve is a reliable Safety Valve Supplier in Egypt, providing critical pressure relief solutions for industrial systems handling steam, gas, and liquid media. Our valves are engineered to automatically release excess pressure and prevent catastrophic failures in pipelines, vessels, and heat exchangers. Designed for quick response and accurate lift, they meet stringent global safety standards and are available in a wide range of sizes and configurations.

Function & Working

Safety valves are pressure-activated devices that open when system pressure exceeds a preset limit. Once activated, they discharge excess fluid to the atmosphere or a discharge line until the pressure returns to a safe level, ensuring protection for personnel, equipment, and processes.
