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.
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.
May 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.
Duckbill 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).
The EPA rigorously tested the Tideflex® Duckbill Check Valve for two years and found that the valve showed “Significant improvement over flap gate valves in terms of leakage inflow, entrapment of debris, capability to self clean and susceptibility to marine fouling.”
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.
