J&S HedFlex Duckbill Check Valve Sizes 1”-96” Series 9800
Model DBV-09-FL is designed to bolt to flanges. J&S HedFlex Check Valves are constructed with superior high grade rubber and superior polyester reinforcement to improve performance, operation, and life expectancy. There are many grades of rubber that vary in chemical make-up. The elastomer’s chemical make-up “the recipe“ determines cost, characteristics, durometer (hardness and stiffness), and quality of the rubber parts used to construct HedFlex Check Valves.
