J&S HedFlex straight duckbill check valves are the solution for faulty flap valves and curved duckbill checks. The curved duckbill, like a flap valve, has to swing open to allow flow. If there is an obstruction in front of these valves, they cannot open. This valve opens and allows flow around obstructions.
