This valve automatically restricts or stops flow when downstream flow exceeds a safe threshold, protecting equipment and personnel from sudden line breaks or disconnections. Constructed from aluminum, the SV804 features female NPT connections on both ends, allowing straightforward inline installation without additional fittings. Pipe size is 1\/2 inch. Licensed contractors and industrial maintenance technicians install this type of valve in compressed air, gas, or fluid systems where excess flow protection is required by code or best practice.\u003c\/p\u003e\n\u003cp\u003eThe SV804 is suited for inline applications in compressed air distribution systems, pneumatic tool supply lines, and similar trade installations. The FNPT x FNPT end connections make it compatible with standard threaded pipe and fittings in 1\/2 inch configurations. Typical use cases include shop air systems, industrial fluid lines, and any application where automatic shutoff on excess flow provides a safety benefit. This valve is appropriate for both light commercial and industrial service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSafety excess flow check valve automatically restricts flow on downstream line failure\u003c\/li\u003e\n  \u003cli\u003eInline body style fits directly into existing 1\/2 inch pipe runs\u003c\/li\u003e\n  \u003cli\u003eFemale NPT x Female NPT end connections for standard threaded pipe compatibility\u003c\/li\u003e\n  \u003cli\u003eAluminum body construction for lightweight, corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch width for compact installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline safety excess flow check valve for 1\/2 inch threaded pipe systems using FNPT x FNPT connections in pneumatic and fluid distribution applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed pipefitter, plumber, or industrial maintenance technician. Depressurize and isolate the line completely before removing any existing fittings or installing this valve. Apply appropriate thread sealant or PTFE tape to NPT threads in accordance with system requirements and applicable codes. Verify flow direction and rated working pressure of the system before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Safety Excess Flow Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Inline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141622\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COILHOSE PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SV804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51560118878514,"sku":"SV804","price":79.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5efd3a3dd9132582d5dee5e8f4b26cff.jpg?v=1786446958","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-sv804-excess-flow-check-valve-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
