- 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) flowsMar 7, 2024 · Explore the ingenious mechanism of duckbill check valves, essential components in fluid systems. Learn how they prevent backflow and the importance of maintenance for optimal performance.
May 8, 2018 · The duckbill is unable to open and remains closed despite the pressure exerted upon it. This means that water cannot move in two directions; it can only move forward. That said, it will be necessary to properly install the inline duckbill check valve and avoid these common mistakes.
Oct 29, 2019 · Silent or spring –assisted check valves do not rely on gravity or reverse flow to close. Instead, the spring closes in about one-tenth of a second, the valve before reverse flow has an opportunity to slam the valve shut.
May 25, 2022 · When the external pressure of the valve is greater than the pressure of the valve pipeline, the duckbill check valve will automatically close to prevent backflow. Usually, a 3m deep water application can reach zero leakage, in an 8m deep water application the valve can still work normally.

Dec 3, 2020 · The phenomenon known as water hammer, also known as valve slam, is when flow reverses before the valve is completely closed. Once the valve has closed, the sudden change in flow direction and the velocity results in water hammer. Water hammer proceeds when water in motion is suddenly forced to stop.
