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 · 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.
Mar 7, 2024 · If the upstream pressure falls below the cracking pressure or there is back pressure (flow attempting to move from the outlet to the inlet), the check valve will close. Typically, check valves have a gate, ball, diaphragm, or disc that is pressed against a seal to close the check valve.
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.
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).
Compared to traditional swing check valves or spring-loaded poppet valves, duckbill valves offer several advantages: No mechanical hinge or spring to fail or wear out, giving them superior reliability and service life. Low cracking pressure and high flow rate due to streamlined design. Tight sealing even around suspended solids and minimal leakage.
