The outlet is one size larger than the inlet to ensure high discharge flow rates. It has a separate seal seating from the diaphragm with a cover that is made from OT58 brass. Available in a variety of sizes to suit most installations, it also has a pressure range from 2.5 bar to 5.0 bar with the response pressure indicated on the twist cap. The valve size is determined by the heat output of the boiler as shown in the maximum heating capacity table.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Kings Plumbing Supplies Limited","offers":[{"title":"1 1\/4\" x 1 1\/2\"","offer_id":46496906313995,"sku":"RWC00002730","price":150.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/9546\/2667\/files\/RWC00002730.jpg?v=1737561262","url":"https:\/\/plumblikeaking.co.uk\/products\/rwc-100-series-high-capacity-heating-pressure-relief-expansion-valve-4-bar-1-1-4-fbsp-x-1-1-2-fbsp-prel100034","provider":"Kings Plumbing Supplies Limited","version":"1.0","type":"link"}
