Click here for manufacturer's website J & S Valve combines the highest quality materials available in an AWWA Gate Valves, C509 & C515 Resilient Seated Gate Valve. J & S offers Ductile Iron Body, Bonnet, Wedge and Gland where as the AWWA Specifications allow for Cast Iron. Cast Iron (Class B) has approximately 1% elongation verses ductile iron which has approximately 9% elongation. The tensile strength of Cast Iron is 31,000 psi. The tensile strength of Ductile Iron is 65,000psi. Since Cast Iron has less elongation than Ductile Iron, it can rupture under less pressure than Ductile Iron. When pressure surges occur in a system, Ductile Iron Valves can withstand higher pressure surges than Cast Iron Valves. The Ductile Iron Wedge is totally encapsulated with EPDM Rubber verses Buna-N. EPDM is more resistant to Chlorine and Chloramines which are used in high concentration in Reuse Water Systems. J & S standardizes on Stainless Steel Stem that has a tensile strength of 64,000psi which is twice as much as Bronze Stems. This selection of materials along with Stainless Steel Fasteners and NSF/ANSI 61 Approved Fusion Bonded Epoxy coating* on the interior of the valves, the exterior of the valves and on the handwheel or 2" operating nuts assures the End-User a robust, long lasting, maintenance free valve. J&S Valve is the Most Complete Line of AWWA Gate Valves in America. |

 J&S HedFlex Duckbill Check Valve Sizes 1" - 96" 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. |
