Reverse Circular Scored Rupture disk

Reverse Domed Scored Rupture Disk is designed with a cross or circular scored line build-up on the concave side of the disk. The disk reverses and opens along pre-weakened cross-scored lines to provide a full relief opening at its burst pressure. Circular-scored lines on concave side with vacuum support. At burst pressure, the disk reverses and opens by shearing around the circular-scored line . Features Non-fragmenting design, suitable for safety valve isolation.Optimum fatigue resistance in pressure pulsating or cycling conditions.Withstand full vacuum without vacuum support.Maximum operating pressure up to 90% of minimum burst pressure.
