The disk is rated to burst at 65 psig, providing a clearly defined relief point for process vessels and pipelines. Available in the sanitary RLS-S and RLS-ST configurations, it supports clean-in-place and hygienic processing environments found in pharmaceutical, food and beverage, and cosmetic manufacturing. As a non-reclosing safety device, the disk activates once the rated pressure is exceeded, providing rapid venting before requiring replacement after discharge. The A000561-1 designation identifies this specific disk profile within BS\u0026amp;B’s RLS family, ensuring compatibility with BS\u0026amp;B sanitary installations and standard 4-inch line sizes. Typical applications include protection of vessels and piping in chemical processing and other high-purity processes where maintaining product integrity and rapid relief are essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"BS","offers":[{"title":"New","offer_id":51677410525486,"sku":null,"price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_551a7238-4997-439d-9f29-b18a2733034b.jpg?v=1769562519","url":"https:\/\/plgautomation.com\/products\/bs-b-a000561-1-rupture-discs-for-pressure-relief","provider":"PLG Automation ","version":"1.0","type":"link"}
