Abstract: A pressure relief device (10) with an integrally attached rupture disk (16) is disclosed. The pressure relief device includes a valve body (12). The valve body includes an inlet (18) and an outlet (20) defining a flow passage therebetween. A valve mechanism (14) is housed in the valve body and is movable between a closed position where it blocks the flow passage and an open position. A rupture disk configured to burst when exposed to a predetermined pressure is provided. The rupture disk is integrally attached to the valve body to prevent the pressurized fluid from flowing through the flow passage until it bursts. Integrally attaching the rupture disk to the valve body makes them a compact unit to be replaced and discarded together. The rupture disk may be integrally attached to the valve body by welding, soldering, brazing, crimping, or adhesive bonding.
