Swing check valves are used to prevent reversal of flow in horizontal pipe lines.FMC does not recommend the use of swing check valves in vertical pipelines, however when using this style of valve in a vertical application the valve must be installed for upward flow only.   Recommended piping practice dictates that check valves be installed with a minimum of 10-15 pipe diameters distance between the check valve and any adjacent flange fitting or pump, otherwise flow fluctuation can result in damage to the valve or piping.   Features There is no tendency for the seating surfaces of swing check valves to gall or score, because the disc meets the flat seat squarely without rubbing contact upon closing. FMC cast steel swing check valves are internally hung design and cannot be supplied with outside lever and weight features. This eliminates additional possible leak paths Body and cover joint: Accurately machined, fully-enclosed gasket.   Valve Design Details Design BS :1868 /ANSI B16.34 /API 6D Face to Face ANSI B 16.10 FLange ANSI B 16.5 R.F TestingBS : 6755 PART -1 / BS:5146
