{"product_id":"qbp342201","title":"Emp Check Valve Kit Engineered Marine Products (21-02382)","description":"\u003cp\u003eA check valve is a device that only allows fluid to flow in one direction. There are two ports on this valve: one for the media inlet and one for media output. A check valve's principal purpose is to prevent backflow in the system. Because they only allow material to flow in one direction, they are commonly referred to as \"one-way valves\" or \"non-return valves.\" A pressure differential is required for a check valve to function. More pressure is applied to the input side of the valve than to the output side to open it. The valve closes when the pressure on the output side is higher (or when the pressure on the input side is insufficient). The closure mechanism differs depending on the valve type.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBackflow prevention kits are usually present in situations where backflow is a concern.\u003c\/li\u003e\n\u003cli\u003eIt has high corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eThis device's materials are strong and long-lasting.\u003c\/li\u003e\n\u003cli\u003eIt can resist temperature fluctuations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpecifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: 21-02382\u003c\/li\u003e\n\u003cli\u003eUPC: 840080481913\u003c\/li\u003e\n\u003cli\u003eWeight: 0.03 LBS\u003c\/li\u003e\n\u003cli\u003eAlternate Products SKU: \"17997A1\", \"REC24-17997A1\", \"18-2715\", \"21-02382\"\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number (MPN): 21-02382\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cbr\u003e\n\u003ch4\u003eThis product replaces:\u003c\/h4\u003e\n\u003cul\u003e840080481913, 24-17997A, 1\u003c\/ul\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e21-02382\u003c\/span\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":53771265900725,"sku":"QBP342201","price":6.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1097715_qbp342201jpg.jpg?v=1794649594","url":"https:\/\/www.qualityboatparts.com\/products\/qbp342201","provider":"Quality Boat Parts","version":"1.0","type":"link"}
