J&S Valve HedFlex - Model Series 9800 - Duckbill Check Valve, Flange
Series 9800 is designed to bolt to flanges. Available as in-line and flange by flange. See drawing link below for all 3 flange type Hedflex Duckbill Check Valves. 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.
