J&S Valve introduces the HedFlex Rubber Duckbill Check Valves. The valves are custom manufactured with high-grade polyester reinforced rubber. It discharges water, slurry or air under low flow and can prevent backflow up to 300 psi. HedFlex is ideal for outfalls, tank overflows, effluent diffusers, course bubble diffusers and mixing. It does not require a proprietary curved bill to close tight. High-grade rubber and reinforcement is how the valve maintains its memory and strength.
