Our experience of rubber check valve installations in wild Atlantic coastal sites since 1990 is unique. We offer full design and installation support for duckbill and inline rubber non return valves.

We currently stock over 700 valves for fast delivery from our bases in the UK and Ireland in sizes from 18mm-1200mm.

Check-Flex valves are available in both Inline and Duckbill valves for the optimal backflow prevention in all locations.

Guvnu fabricated valves simplify installation for replacing failed metal valves and extend the available size of rubber check valves to 3000mm

Reliable backflow prevention is an essential element of modern drainage design, maximising gravity flow and ensuring network attenuation is available for storm events.
