- What Are The Benefits?
By controlling and preventing backflow, check valves prevent discharges from wastewater treatment plants from contaminating clean water supplies. Check valves can also help prevent flooding, standing water, ensure water flows in the correct direction and prevent potentially harmful phenomena such as water hammers. In addition, check valves are wide...
There are also potential health and environmental impacts. In many urban environments, excess stormwater is drained into the existing sewerage system, where the network can become overwhelmed, resulting in the backflow and overflow of contaminated water.
The unique design prevents backflowPassive non-mechanical operation and negligible maintenance and energy costsEasy installation on all existing infrastructureResistant to corrosion, fire and abrasive (sludge) flowsMay 1, 2024 · When compared to conventional check valves, duckbill valves offer several distinct advantages: Enhanced Durability Built to withstand corrosive and abrasive conditions, they outlast many traditional check valves, reducing long-term replacement costs.
Jun 6, 2023 · The duckbill check valve is a flexible sleeve shaped like a duck’s beak. It allows forward flow of water with positive head differential pressure which progressively opens the valve as flow increases. Duckbill check valves consistently provide the tightest seal for preventing backflow.
