{"product_id":"brass-metal-seated-swing-check-valves","title":"Brass Metal Seated Swing Check Valves","description":"\u003cp\u003eBrass Metal Seated Swing Check Valves are designed to prevent reverse flow in pipework systems, ensuring fluid moves in one direction only. Commonly used in plumbing, heating, and mechanical installations, they provide a simple, automatic solution for backflow prevention without the need for manual operation.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eThese valves operate using a hinged internal disc that swings open under forward flow and closes automatically when flow stops or reverses. This design allows for a full flow path with minimal pressure loss, while providing reliable shut-off against backflow.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eConstructed from durable brass with a metal-to-metal seat, these valves offer enhanced temperature resistance and long service life compared to soft-seated alternatives. The metal seat design is particularly suited to applications where durability and resistance to wear are important, although slight seepage can occur under sustained reverse pressure due to the nature of metal seating.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eTypically supplied with BSP threaded connections, they integrate easily into standard pipework systems and are suitable for a wide range of general-purpose applications.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cp\u003e• Swing check (non-return) design for automatic backflow prevention \u003cbr\u003e• Metal-to-metal seat for durability and higher temperature resistance \u003cbr\u003e• Brass body construction for corrosion resistance and long service life \u003cbr\u003e• Full flow design for minimal pressure drop \u003cbr\u003e• BSP threaded connections for easy installation \u003cbr\u003e• Suitable for horizontal installation (vertical possible depending on system design) \u003cbr\u003e• Rated typically up to PN16 (size dependent) \u003cbr\u003e• Low-maintenance, reliable operation\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eApplications\u003c\/h4\u003e\n\u003cp\u003eWater distribution systems, heating and HVAC installations, plantrooms, compressed air systems, and general industrial pipework where prevention of reverse flow is required.\u003c\/p\u003e","brand":"Fire-Mech Fixings","offers":[{"title":"15mm","offer_id":54187252187469,"sku":"SWCVB015","price":16.72,"currency_code":"GBP","in_stock":true},{"title":"20mm","offer_id":54187252220237,"sku":"SWCVB020","price":18.85,"currency_code":"GBP","in_stock":true},{"title":"25mm","offer_id":54187252253005,"sku":"SWCVB025","price":20.82,"currency_code":"GBP","in_stock":true},{"title":"32mm","offer_id":54187252285773,"sku":"SWCVB032","price":30.07,"currency_code":"GBP","in_stock":true},{"title":"40mm","offer_id":54187252318541,"sku":"SWCVB040","price":36.4,"currency_code":"GBP","in_stock":true},{"title":"50mm","offer_id":54187252351309,"sku":"SWCVB050","price":51.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/9925\/1021\/files\/SWCVB025_282e1c5f-60ab-4f62-8b4a-234660ce8a8e.png?v=1782816733","url":"https:\/\/fire-mechfixings.co.uk\/products\/brass-metal-seated-swing-check-valves","provider":"Fire Mech Fixings","version":"1.0","type":"link"}
