The valve is designed to be fitted in the upper portion of the cylinder as this is where the hottest system temperatures will be found. If the system temperature rises beyond 95°C, the wax mixture within the element of the temperature probe will expand, causing the valve to lift off its seat and relieve water to waste. If the water pressure increases (without temperature increase) the valve will stay closed until the set pressure of the relief mechanism is reached, at which point the valve will open to relieve the excess pressure build-up.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"ijrfc\"\u003e\n\u003ch4 id=\"irxzg\"\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul id=\"ifjd2\"\u003e\n\u003cli id=\"in60w\"\u003e1\/2\" MBSP threaded (Inlet) x 15mm compression (Outlet) connections\u003c\/li\u003e\n\u003cli id=\"i2pni\"\u003eCartridge construction provides a longer life span and service of the valve\u003c\/li\u003e\n\u003cli id=\"iz1rp\"\u003e95mm Probe length\u003c\/li\u003e\n\u003cli id=\"i8edl\"\u003e4.5 Bar temperature pressure relief valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cell\" id=\"ikl0c\"\u003e\n\u003cdiv id=\"i8wwg\"\u003e\n\u003ch4 id=\"i63lg\"\u003eSpecification\u003c\/h4\u003e\n\u003cul id=\"ig2iw\"\u003e\n\u003cli id=\"imp5p\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"iqets\"\u003eConnection:\u003cspan draggable=\"true\" id=\"ici2g\"\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e1\/2\" MBSP threaded (Inlet) x 15mm compression (Outlet)\u003c\/li\u003e\n\u003cli id=\"i3fzt\"\u003e\n\u003cstrong draggable=\"true\" id=\"iy0rm\"\u003eBrand: \u003c\/strong\u003eReliance Water Controls (RWC)\u003c\/li\u003e\n\u003cli id=\"ie1op\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"iuoii\"\u003eRange:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eCPT15\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"iabak\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"ivoyh\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"i592o\"\u003ePressure Settings (Set \u0026amp; Locked):\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e4.5 Bar\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"i1yve\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"iyt1zp\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"ivrqwe\"\u003eTemperature Relief:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e90-95°C\u003c\/li\u003e\n\u003cli id=\"i5tgk\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"ixcef\"\u003eDischarge:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e10kW\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"iiewj\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"id3o6\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"ila9c\"\u003eProbe Length:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e95mm\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"ifvt1\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"ia2rj\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"ijd4e\"\u003eMaterial:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eBrass Body\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"iaake\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"ii1o5\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"iziyb\"\u003eCertifications:\u003c\/strong\u003e WRAS Approved\u003cbr data-highlightable=\"1\" draggable=\"true\" id=\"iybff\"\u003e\n\u003c\/li\u003e\n\u003cli id=\"i42qj\"\u003e\n\u003cstrong data-highlightable=\"1\" draggable=\"true\" id=\"i3dst\"\u003eReplaces:\u003c\/strong\u003e TPR15\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Kings Plumbing Supplies","offers":[{"title":"1\/2\" x 15mm","offer_id":46472458961163,"sku":"RWC00001380","price":29.68,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/9546\/2667\/files\/RWC00001380_eaf88b22-aa10-4df8-b9b3-c019c94f1ab8.jpg?v=1772756858","url":"https:\/\/plumblikeaking.co.uk\/products\/rwc-cpt15-pressure-temperature-relief-valve-4-5-bar-1-2-mbsp-x-15mm-ptem540015","provider":"Kings Plumbing Supplies Limited","version":"1.0","type":"link"}
