Working Principle

LC Series Discs mount with the concave surface facing the process media. As pressure increases above the recommended operating ratio,the score lines weaken until rupture occurs.When the LC Disc ruptures,the Disc opens along the score lines and folds back against the holder outlet.

Protection of Safety relief valve

 • Use of rupture discs in combination with relief valves can prevent corrosion of the relief valve internals.
