Abstract
The experimental loop was designed and installed to measure the disc positions, disc back stop load and differential pressure with flow velocity for 3 inch and 6 inch swing check valves. The tests were performed at various conditions of upstream flow disturbance source and distance from the tested check valves to investigate the effect of the upstream flow conditions on the disc stability of the swing check valves. The selected disturbance sources were elbow, globe valve, and orifice. The experimental results are presented herein.
