KECKLEYStyle DD07/11Wafer Double Disc Check ValveCast Iron (ASTM A 126, Class B)125 lb.APPLICATIONSLiquid or gas where protection from flow reversal in a pipeline isrequired.Carbon Steel (ASTM A 216, Grade WCB)150 lb. Thru 1500 lb.Stainless Steel (ASTM A 351, Grade CF8M)150 lb. Thru 1500 lb.CONSTRUCTIONThe Keckley Wafer Double Disc Check Valves are constructed fromrugged castings that are machined to exacting specifications. Referenceindividual technical data pages for standard disc, shaft, spring, andelastomer seat.FEATURES A short face-to-face dimension. Lighter weight, by 80-90% than non-conventional full-body checkvalves. Spring-loaded, double disc design has a low cracking pressure. The tension spring performs a lifting motion on the disc to preventexcessive wear on the “heel” area of the elastomer seat. The independent, dual shaft design allows interchangeability ofshafts. The stop shaft stabilizes the discs during high flow rates. Epoxy coating is standard. Field serviceable without the need for special tools.Style DLINSTALLATIONThe Keckley Wafer Double Disc Check Valves are used in bothvertical and horizontal applications. For horizontal flow applicationsthe shaft should be vertically oriented. Contact Keckley for downwardvertical flow installations.ORDERINGReference page C2 for Keckley Check Valve Product Numbers.WORKING PRESSURES – NON SHOCKNOM. RATINGStyle DF125#NOM. RATING150#NOM.
