Duckbill Valve Features
Duck Bill Valves are also known as rubber check valves, back pressure flexible check valves, duck bill valve check valves, rubber check valves, rubber check valves, and rubber slow closing check valves.
Duck Bill Valve Material: Can made of food grade silicone or rubber material. Without internal pressure, the duckbill exit closes under its own elasticity as internal pressure gradually increases, and the duckbill exit gradually increases while the liquid is escaped at a high flow rate.
The valve opens when the fluid gas passes through the valve.
The increased flow and pressure also increases the opening of the duckbill valve.
Backwater pressure or atmospheric pressure will push down on the duckbill valve firmly to prevent fluid and gas backflow when water is stopped.
The pressure required to open the duckbill valve is very small. The pressure of the small duckbill valve is generally 1 to 5 KPA. For convenient opening and closing of the duckbill valve and good sealing, it can effectively prevent backflow. Meets application requirements in liquids, gas, and many fields. For example, medical equipment, machinery, and equipment daily necessities, electronics, equipment irrigation, animal industry, etc.
