Duck bill valve is also known as a rubber check valve a back pressure flexible check valve a duckbill valve check valve a rubber check valve and a rubber slow closing check valve. Duckbill valve material can use food grade silicone or rubber material In the absence of internal pressure the duck bill outlet closes under its own elasticity as the internal pressure gradually increases the duck bill outlet gradually increases keeping the liquid drained at high flow rates. The valve opens when the appropriate pressure fluid gas passes through the valve. When the flow rate or pressure increases the opening degree of the duckbill valve also increases When the water flow stops the backwater pressure or atmospheric pressure will press the duckbill valve tightly to prevent backflow of liquid or gas The pressure required to open the duckbill valve is very small The pressure of the small duckbill valve produced is generally 1-5KPA Due to the convenient opening and closing of the duckbill valve and good sealing it can effectively prevent the backflow of liquid and gas and meet the application requirements in many fields For example machinery, and equipment daily necessities electronic, equipment irrigation, animal husbandry etc.
