The drainage & sewage backwater protection
VALVES/NON-RETURN AND FLAP VALVES
- Reliable and Durable:
High mechanical strength due to Glass Reinforced Plastic (GRP) construction.
Design is verified by Finite Element Stress Analysis.
Resistant up to 1 bar (10 m head) and back pressure (0,6 to1,0 bar by model).
Integral rubber seals easily replaced if damaged.
Fast and easy installation.
Most sizes can be handled by one person.
Very low operating pressure (cracking head) compared with metal flap valves.
- Corrosion Resistant:
Highly resistant to corrosion and UV degradation.
No coatings needed.
- Low Maintenance:
Long service life and low maintenance.
Conforms to ISO 9001 quality standards.
