For Instructional Manual click here Description Burst Disks MDC Burst Discs are designed as a safety device to protect vacuum systems against over-pressurization during back-fill or from an accidental increase in pressure due to a system malfunction. BDA-series ASME UD certified burst disks feature all-metal stainless steel construction and are designed for use in UHV applications. Application Most vacuum vessels are designed and constructed with internal vacuum joints and welds that are rated for an external load of one atmosphere. They are not pressure vessels and as such should not be subjected to positive pressure loads in excess of 1-ATM. For this purpose MDC has developed a new line of BDA disks that are ASME certified to prevent the accidental pressurizing of a vacuum vessel. MDC burst disks are offered with either 1.33 or 2.75 Del-Seal™ (CF style) metal seal flange connections. They can be fitted to any vacuum system where over pressurization is a concern. Improved Design MDC's BDA-series burst disks have been re-engineered to be 10CFR851 compliant. They are constructed with a frustum designed metal membrane which is capable of sustaining a vacuum load. As pressure inside a vacuum vessel reaches 11.5 PSIG the disk membrane activates and fully opens, relieving the pressure in the system. The disk membrane is circular scored preventing fragmenting upon rupture and thus does not pose harm to local personnel or equipment. Once activated, the disk is not reusable and must be replaced to restore the vessel to an operational condition.
