Capricorn non-return valves are designed for installation on horizontal pipe segments in sewage manholes either inside or outside buildings. Non-return valves provide anti-flooding protection and help to protect buildings against flooding due to rainwater travelling back down the sewage system. Capricorn non-return valves are automatically operated, providing free waste water drainage according to the slope of the rainwater drain.
We offer type I and type IV non-return valves with one flap and type II non-return valves with two flaps with Duo Protect system to ensure double protection based on two automatically closed protection flaps.
Capricorn non-return valves have been awarded the TÜV Rheinland Certificate of Conformity T+M!

- non-return valves with one flap: Ø50 – Ø200
- non-return valves with two flaps: Ø110 – Ø200
