PRODUCT SELECTION GUIDE TENSION TYPE RUPTURE DISCS REVERSE ACTING RUPTURE DISCS TYPE OF DISC Process Side Process Side Fig. B Reverse Acting Rupture Discs are oriented in a system with the process media pressure against the convex side of the disc (Figure C), placing the rupture disc in compression. As the burst pressure rating of the disc is reached, the compression loading on the rupture disc causes it to reverse, snapping through the neutral position and causing it to open by a predetermined scoring pattern. Process Side Tension Type Rupture Discs are oriented in a system with the...
