Built with a brass body and brass seal, this valve is rated at 200 WOG (water, oil, gas) and connects via C x C (copper sweat) end connections. It is suited for plumbing and light mechanical systems where backflow prevention is required. The swing-type disc design opens under forward pressure and closes by gravity and reverse flow, making it a reliable passive component for residential and commercial water lines. Plumbers and pipefitters are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThis valve is intended for use in copper pipe systems at 1\/2 inch pipe size. Typical applications include domestic water supply lines, hydronic heating circuits, and general plumbing installations where flow directionality must be controlled. The 200 WOG pressure rating makes it appropriate for standard service pressures found in residential and light commercial plumbing systems. It is packaged as a single unit and is suitable for direct replacement or new installation work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSwing check design passively prevents backflow without external actuation\u003c\/li\u003e\n\u003cli\u003eBrass body and brass seal construction for corrosion resistance in wet service environments\u003c\/li\u003e\n\u003cli\u003e200 WOG pressure rating suitable for water, oil, and gas service\u003c\/li\u003e\n\u003cli\u003eC x C end connections for solder-joint installation on standard copper pipe\u003c\/li\u003e\n\u003cli\u003eMaterial grade 46400 brass for consistent alloy quality\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 2.75 inches tall and 1.75 inches in width and length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install component for 1\/2 inch copper pipe systems using C x C (sweat) end connections rated for 200 WOG service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) requirements. Shut off the water supply and fully depressurize and drain the line before cutting into existing pipe. Use proper flux and lead-free solder for all sweat connections, and observe local code requirements regarding solder composition for potable water systems. Verify flow direction marked on the valve body before soldering to ensure correct orientation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Swing Check\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x C (Copper Sweat)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 200 WOG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 46400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-503NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691454988594,"sku":"101-503NL","price":19.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae2421f7989f1525a94274478db9f038.jpg?v=1788285297","url":"https:\/\/voomisupply.com\/products\/value-collection-101-503nl-brass-swing-check-valve-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
