Mar 17, 2022 · Duckbill check valves are non-mechanical, require no maintenance, and do not slam when closed. They are also resistant to organic contaminants such as algae and barnacles and have no problem disposing of suspended solids entrained streams, such as abrasive slurries.
Mar 7, 2024 · When fluid pressure exceeds a certain threshold in the desired direction, it forces the slit of the valve open, allowing unimpeded flow. This process occurs seamlessly without external intervention, making duckbill check valves inherently passive and low-maintenance components.
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.
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.
May 1, 2024 · Self-Cleaning Capability. The valve’s unique closing motion naturally dislodges debris, reducing the risk of clogging and ensuring it stays clear and functional. Clog-Free Operation. Its flexibility allows solids to pass through effortlessly, minimizing blockages even in challenging flow conditions. Minimal Maintenance.
Feb 22, 2016 · Duckbill Check Valve - The flexible rubber duckbill valve is normally closed but will open with very minimal head pressure, always providing maximum flow with minimal pressure drop across the valve. This valve will even handle large obstructions without jamming or binding, and guarantee trouble free back flow prevention, and can even seal ...
