Anti-flood valves

Home→ Catalog→ Sewerage→ Domestic sewerage→ Anti-flood valves

Check valves are protective pipeline fittings. Check valves are designed to eliminate the possibility of backflow of water. They are able to completely block the flow of the working medium if necessary.

The design of the check valve is quite simple and consists of several elements:

  • inlet and outlet pipes;
  • lever for forced withdrawal of wastewater;
  • membranes for closing pipelines;
  • cleaning covers.

Here you can buy high-quality check valves for sewer systems from well-known manufacturers: HL, Wawin and Ostendorf.
