This specification covers all labor, materials, equipment and services necessary to <br />complete the installation of the Checkmate Inline Tideflex check valve, or Equal as <br />specified. <br /> <br />1.2 SUBMITTALS <br /> <br />A. Submit product literature that includes information on the performance and operation of <br />the valve, materials of construction, dimensions and weights, elastomer characteristics, <br />flow data, headloss data, and pressure ratings. <br /> <br />B. Upon request, provide shop drawings that clearly identify the valve dimensions. <br /> <br />C. Upon request, manufacturer shall provide installation and reference lists for existing <br />valves of similar size and type to the project scope. <br /> <br />1.3 QUALITY ASSURANCE <br /> <br />A. Manufacturer shall have at least fifteen (15) years of experience in the production of <br />elastomer “Duckbill” style elastomeric valves. <br /> <br />B. Manufacturer shall have conducted independent hydraulic testing to determine headloss <br />and jet velocity characteristics. The testing must include multiple constructions (stiffness) <br />within each size and must have been conducted for free discharge (discharge to <br />atmosphere) and submerged conditions. <br /> <br />C. Manufacturer shall have conducted an independent hydraulic test where multiple valves <br />(at least four) of the same size and construction (stiffness) were tested to validate the <br />submitted headloss characteristics and to prove the repeatability of the manufacturing <br />process to produce the same hydraulic characteristics. <br /> <br />D. Valves 48” and larger must incorporate a metallic support completely encapsulated in the <br />wall thickness at the top portion of the valve to assist in supporting the weight of the valve.
