In the Top Hat Assembly, the disc is welded directly to the top hat, creating a single-piece welded tee design. Leakage at the seating area of the rupture disc assembly is eliminated. The assembly's overall design prevents product build up as it reduces resistance to flow while still providing flowing fluid over the rupture disc surface. The disc is placed as close to the flow as possible to further reduce product buildup. As an additional benefit, standard piping and flanges replace the diaphragm valve body, making the top hat a more affordable solution than using diaphragm valves.
