The spring cartridge assembly can be supplied separately for use as an integral pump bypass relief valve. The spindle is fitted with an ‘O’ ring to protect the spring, particularly on corrosive duties.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSizes:\u003c\/strong\u003e 3\/4\", 1\", 1.1\/2\", 2\"\u003cbr\u003e\u003cstrong\u003eConnections: \u003c\/strong\u003eBSP Male Inlet x BSP Female Outlet\u003cbr\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e Bronze body\u003cbr\u003e\u003cstrong\u003eDisc:\u003c\/strong\u003e Bronze\u003cbr\u003e\u003cstrong\u003eJoints \u0026amp; Seals:\u003c\/strong\u003e Nitrile spindle O ring\u003cbr\u003e\u003cstrong\u003eMedium:\u003c\/strong\u003e Liquids \u003cbr\u003e\u003cstrong\u003eSet Pressure:\u003c\/strong\u003e 0.35 to 24 Barg\u003cbr\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e -20 to +120 degC Max\u003c\/p\u003e\n\u003ch5\u003eDatasheets\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0998\/0218\/files\/bailey-480-relief-valve-datasheet.pdf?16336239561653575517\" title=\"Bailey 480 Cartridge Assembly Relief Valve Datasheet\" target=\"_blank\"\u003eBailey 480 Cartridge Assembly Relief Valve Datasheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0998\/0218\/files\/bailey-safety-relief-reducing-valve-brochure.pdf?16173068698907620281\" title=\"Bailey Safety Relief and Reducing Valve Brochure\" target=\"_blank\"\u003eBailey Safety Relief and Reducing Valve Brochure\u003c\/a\u003e\u003c\/p\u003e","brand":"Bailey","offers":[{"title":"3\/4\" (DN20)","offer_id":53084638708048,"sku":"BA-480-20","price":301.75,"currency_code":"GBP","in_stock":true},{"title":"1\" (DN25)","offer_id":53084638740816,"sku":"BA-480-25","price":351.05,"currency_code":"GBP","in_stock":true},{"title":"1.1\/2\" (DN40)","offer_id":53084638773584,"sku":"BA-480-40","price":455.6,"currency_code":"GBP","in_stock":true},{"title":"2\" (DN50)","offer_id":53084638806352,"sku":"BA-480-50","price":585.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/2344\/3024\/files\/bailey_480_relief_valve_c7ee38ad-cb4a-41df-a0bd-2f8500eed378.png?v=1788880722"},{"product_id":"nabic-500l-pressure-relief-valve","title":"NABIC 500L Pressure Relief Valve","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003eThis is a stock item.
