The 3\" nominal disk, part of the S-90 family and cataloged as 1172726 (VD-Y-05), is specified as 290 PSIG at -20°F, making it suitable for environments where low-temperature performance is required. It is intended for upstream installation with BS\u0026amp;B safety heads such as SRI-7RS, SRB-7RS, or S90-7R to protect downstream equipment from overpressure events. The S-90 disks are offered in a range of corrosion‑resistant materials, including 316 stainless steel, Nickel 200, Monel 400, Inconel 600, Hastelloy C-276, and other stainless variants, allowing selection for diverse chemical services. In BS\u0026amp;B catalogs, 3-inch S-90 disks have material-dependent burst ranges (for example, Nickel 200 versions list a broad burst-pressure window around 75–350 psig at 72°F, with Inconel 600 versions up to about 350 psig), illustrating the importance of selecting the correct material for the intended service temperature and chemistry. This VD-Y-05 configuration provides a compact, weld-ready solution that fits BS\u0026amp;B’s Sta-Saf and related safety-head configurations, aligning with standard installation practices for rupture disks in industrial safety systems. \u003c\/p\u003e\u003c\/div\u003e","brand":"BS\u0026B","offers":[{"title":"New","offer_id":51677413212462,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2ed6380e-4292-4727-a70f-7929c0391511.jpg?v=1769562558","url":"https:\/\/plgautomation.com\/products\/bs-b-safety-systems-vd-y-05-rupture-disk-s90-3-inch","provider":"PLG Automation ","version":"1.0","type":"link"}
