The valve is selected for the required set pressure. As the pressure rises, when the discharge pressure is reached the valve opens and discharges to atmosphere, preventing the pressure within the system reaching levels which would be dangerous for the boiler, hot water storage cylinder and any personnel in the adjacent vicinity.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e 3\/4\" x 3\/4\"\u003cbr\u003e \u003cstrong\u003eConnections:\u003c\/strong\u003e BSP Female Inlet x BSP Female Outlet\u003cbr\u003e \u003cstrong\u003eMaterials:\u003c\/strong\u003e Brass\u003cbr\u003e \u003cstrong\u003eMedium:\u003c\/strong\u003e Air and Water\u003cbr\u003e \u003cstrong\u003eSet Pressure:\u003c\/strong\u003e 3 Barg \u003cbr\u003e\u003cstrong\u003eDischarge Flowrate:\u003c\/strong\u003e 142.1 kg\/hr\u003cbr\u003e \u003cstrong\u003eMax Boiler Rating:\u003c\/strong\u003e 82.5 kW\u003cbr\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e +5 to +110 degC\u003cbr\u003e\u003cstrong\u003eProduct Code:\u003c\/strong\u003e 311530\u003cbr\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e WRAS approved, CE marked\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eDatasheets\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0812\/3452\/6525\/files\/Altecnic-Caleffi-3-4-Inch-F-x-F-311-Series-Safety-Pressure-Relief-Valve-3-Bar-311530.pdf?v=1699306847\" title='Altecnic \/ Caleffi 311 Series Safety Relief Valve 3\/4\" x 3\/4\" F x F 3 bar - 311530 Datasheet' target=\"_blank\"\u003eAltecnic \/ Caleffi 311 Series Safety Relief Valve 3\/4\" x 3\/4\" F x F 3 Bar - 311530 Datasheet\u003c\/a\u003e\u003c\/p\u003e","brand":"Altecnic\/Caleffi","offers":[{"title":"Default Title","offer_id":53084634317136,"sku":"AL-311530","price":13.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/2344\/3024\/files\/Altecnic-Caleffi-3-4-Inch-F-x-F-311-Series-Safety-Pressure-Relief-Valve-3-Bar-311530.jpg?v=1780050643"}],"url":"https:\/\/industrialvalveoutlet.com\/collections\/best-sellers.oembed","provider":"Industrial Valve Outlet","version":"1.0","type":"link"}
