FAQ
Who supplies large rubber duckbill check valves in the UAE?
We at Dutco Tennant LLC supply reliable rubber duckbill check valves designed for harsh drainage, sewage and industrial environments across the UAE and GCC.
What is the lifespan of a duckbill valve?
They have no mechanical parts and resist corrosion, rubber check valves generally deliver long service life even in demanding wastewater conditions.
How often should duckbill valves be replaced?
Replacement is rare. Since flex check valves are self-operating and corrosion-resistant, they only need changing when the rubber loses shape or no longer seals.
What material is used for duck bill valve construction?
Duckbill non return valves are made from durable elastomeric rubber, giving them flexibility, corrosion resistance and reliable sealing under varying pressures.
How do you know if a check valve non return valve needs replacement?
If you notice backflow, leakage, or a deformed rubber sleeve, the valve duckbill is no longer sealing properly and should be replaced.
Why are duckbill valves better than flap check valves?
Duckbill check valves perform better because they have no metal parts to rust or jam. They seal automatically, stay quiet and work well in sewage or sludge.
How does a rubber flap valve prevent backflow?
The flexible sleeve opens with forward flow and closes when pressure reverses. This simple motion creates a tight seal that stops backflow instantly.
Do flex check valves need maintenance?
They are virtually maintenance free. With no hinges or moving parts, the rubber design operates quietly and stays reliable even in corrosive environments.
