4 Note: It is generally recommended that when using the 1126a Swing Check valves that you locate the Valve at least 5 pipe diameters down stream from any flow disturbance or obstruction ( Valve , pump, elbow, reducer, etc.). Turbulence close to the Check Valve may result in Valve chatter resulting in premature failure of the Check Fire Valves2010-12-21 Swing Check Valve ( flanged )1126 AManufactured for Viking SupplyNet by Kennedy Valve , division of mcwane Inc.
