Non-Return Tidal Valves & Backflow Prevention Systems

Stoneman Engineering supplies and installs specialized tidal valves that prevent backflow and tidal surge damage in coastal and riverside locations. Our tidal valve systems provide automatic operation without external power, utilizing ingenious mechanical design to protect drainage systems and prevent flood water ingress.

Our tidal valve expertise covers outfall protection for surface water drainage, sewer system protection against tidal backflow, and culvert installations requiring bidirectional flow control. Each valve is manufactured to site-specific requirements, incorporating features such as debris screens, access hatches, and monitoring capabilities.

Materials selection prioritizes corrosion resistance and mechanical reliability, utilizing stainless steel components and specialized sealing systems designed for continuous submersion in saltwater environments. Our installation teams provide professional fitting with minimal disruption to existing drainage systems.

From residential properties requiring single valve protection to major infrastructure projects with multiple valve installations, Stoneman Engineering delivers tidal valve solutions that provide reliable flood protection through mechanical operation, robust construction, and comprehensive commissioning services.
