Inverted rupture disc RCS®

flat seatreverse actingmetal

Reliable, accurate, easy to install and simple to retrofit into your current piping system – the RCS rupture disc is the clear choice for any gas-only application. A reverse-acting, cross-scored rupture disc, the RCS provides high performance pressure relief for larger sizes than available with the HPX line. High precision, optimum flow We use high-precision manufacturing techniques to create slight indentations on the surface of the RCS dome to ensure it initiates reversal at exactly the specified burst pressure. In addition, the RCS rupture disc’s cross-scored pattern provides a clean, consistent opening pattern and a non-fragmenting four-petal burst design for optimum flow. Corrosion protection Thicker rupture disc materials and optional fluoropolymer liners and coatings (for both vent and process sides) make the RCS highly resistant to corrosion. We also cross-score the vent side of the RCS to prevent process buildup or corrosion along the process side score lines. Safety ratio Should your RCS rupture disc be damaged during installation or handling, it will still provide pressure relief at or less than 1.5 times its rated (marked) burst pressure. The RCS is an ideal choice for primary or secondary system-relief protection and provides an effective means of fugitive emission control when used to isolate a safety relief valve. Optional features The RCS is available to be cleaned for oxygen or chlorine service.
