{"product_id":"trudesign-non-return-valve-check-valve-low-resistance-pressure","title":"TruDesign Non-Return Valve (Check Valve) – Low Resistance Pressure","description":"\u003cp\u003eDesigned and manufactured in New Zealand, the TruDesign Non-Return Valve is a lightweight, corrosion-free way to prevent water backflow or siphoning anywhere in your onboard plumbing system. Moulded from a UV-stabilised, glass-reinforced nylon composite, it combines high strength and impact resistance with a fraction of the weight of a traditional metal valve and can be safely used in direct sunlight without degrading.\u003cbr\u003e\u003cbr\u003eThe valve's construction makes it \"water hammer safe,\" remaining insensitive to sudden pressure shocks within the pipeline, while an internal stainless steel spring ensures reliable, corrosion-free operation with no risk of the valve sticking open over time. A low cracking pressure means minimal force is needed to open the valve, keeping restriction on flow rate to a minimum.\u003cbr\u003e\u003cbr\u003eAs an in-line fitting, it requires minimal installation space and no additional fittings, connecting directly onto hose with clamps at each end. A printed white arrow clearly indicates the direction of water flow for quick, foolproof installation. Please note this is not suitable for use in marine sanitation systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Highlights:\u003c\/strong\u003e\u003cbr\u003e•    UV-stabilised glass-reinforced nylon composite construction\u003cbr\u003e•    Suitable for fresh water pipe systems\u003cbr\u003e•    Corrosion-free stainless steel spring mechanism\u003cbr\u003e•    Water hammer safe, resists pressure shocks\u003cbr\u003e•    Low cracking (opening) pressure\u003cbr\u003e•    In-line fitting, no extra connectors required\u003cbr\u003e•    Clear flow-direction arrow printed on body\u003cbr\u003e•    Available in 5 sizes: 3\/4\", 1\", 1 1\/8\", 1 1\/4\", 1 1\/2\"\u003cbr\u003e\u003c\/p\u003e","brand":"Boat Fittings","offers":[{"title":"3\/4\"","offer_id":57511641153911,"sku":"SM-2282","price":10.03,"currency_code":"GBP","in_stock":true},{"title":"1\"","offer_id":57511641186679,"sku":"SM-2283","price":11.08,"currency_code":"GBP","in_stock":true},{"title":"1  1\/8\"","offer_id":57511641219447,"sku":"SM-2284","price":13.19,"currency_code":"GBP","in_stock":true},{"title":"1  1\/4\"","offer_id":57511641252215,"sku":"SM-2285","price":13.97,"currency_code":"GBP","in_stock":true},{"title":"1  1\/2\"","offer_id":57511641284983,"sku":"SM-2286","price":20.32,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/5679\/9306\/files\/SM-2282-GRP.jpg?v=1791206069","url":"https:\/\/www.boatfittings.co.uk\/products\/trudesign-non-return-valve-check-valve-low-resistance-pressure","provider":"Boat Fittings","version":"1.0","type":"link"}
