Flat Perforated Bursting Disc (PF)

The slotted rupture disk consists of a slotted membrane paired with a sealing diaphragm, with the bursting pressure controlled by weakened structures between the slots. During pressure relief, it opens by tearing along the slots. Suitable for low-pressure applications such as pipelines and vessels, this rupture disk offers excellent sealing performance and a large discharge area. Application areas include: petrochemicals, coal chemical processing, pharmaceuticals, fertilizers, plastics, grain, pigments, pesticides, and tobacco industries.
