Mar 7, 2024 · How Does a Duckbill Check Valve Operate? The operation of a duckbill check valve hinges upon fluid mechanics principles and elastomeric behaviour. When fluid pressure exceeds a certain threshold in the desired direction, it forces the slit of the valve open, allowing unimpeded flow.

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) flowsDuckbill Valves are unique, one-piece, elastomeric components that act as backflow prevention devices. Also known as one-way valves or check valves. They have elastomeric edges, or lips, shaped in a way that resembles a duck’s bill (hence their name).
Jun 13, 2024 · A key characteristic of the duckbill check valve is that it requires no intervention to open or close and operates as a result of a pressure differential across the valve – the pressure from a liquid pushes the two-halves apart allowing the fluid to pass through.
May 4, 2020 · Duckbill Check Valves are unique, one-piece, elastomeric components that act as backward flow prevention devices or one-way valves or check valves. Duckbill check valve enable flow to proceed through a soft tube that feeds into the downstream side of the valve wherein back pressure collapses the tube and cuts off the flow.
Duckbill check valves allow flow in only one direction through a pipe or tube while preventing any backflow in the opposite direction. When fluid pressure is applied from the upstream side, the duckbill flexes open to allow flow.
Duckbill check valves offer several advantages over traditional check valve designs. Firstly, their simple and compact design eliminates the need for mechanical components like hinges and springs, reducing the risk of failure and reducing maintenance requirements.
