- 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) 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).
Check Valve Slam. Check valve slam occurs after pump stoppage when the system flow reverses back towards the pump before the check valve is fully closed (Figure 1). The reverse flow causes the check valve to close rapidly through the remaining portion of its travel.

Mar 7, 2024 · A non slam axial check valve is a valve that closes abruptly because of gravity, causing pressure surge and resulting in shock waves, which can stress the piping system. The non slam check valve prevents backflow of the medium, prevents the pump and drive motor from reversing, and releases the medium of the container.
Cla-Val Rubber-Flex Duckbill Check Valves are designed to provide outstanding back-flow prevention; eliminating costly and unwanted back-flow from rivers, oceans, storm water, and is an excellent choice for sewage diffuser systems.
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.
