The body casting is unleaded bronze with a hex profile machined into the body for easy installation and removal with standard wrenches. Internal components include a non-spin acetal poppet with a Nitrile (Buna-N) seal and a stainless steel spring, giving the valve reliable one-directional flow control and consistent shutoff. This valve is rated to a maximum working pressure of 400 psi. Licensed plumbers and mechanical contractors are the primary installers of this fitting in potable water and industrial piping applications.\u003c\/p\u003e\u003cp\u003eThe 4201e is sized at 1 inch and is suited for residential and light commercial plumbing systems, including potable water supply lines, pump discharge applications, and pressure systems where backflow prevention is needed. The lead-free bronze construction meets requirements for use in systems handling drinking water. The compact body and hex wrenching surface make it well suited for tight installation spaces where a wrench must engage the valve body directly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free unleaded bronze body casting for potable water compliance\u003c\/li\u003e\n\u003cli\u003eHex-shaped body profile allows direct wrenching during installation and removal\u003c\/li\u003e\n\u003cli\u003eNon-spin acetal poppet prevents rotation during operation for consistent seal engagement\u003c\/li\u003e\n\u003cli\u003eNitrile (Buna-N) seal provides reliable shutoff and chemical compatibility\u003c\/li\u003e\n\u003cli\u003eStainless steel spring ensures positive poppet return and backflow prevention\u003c\/li\u003e\n\u003cli\u003eRated to 400 psi maximum working pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment check valve for 1-inch plumbing systems requiring lead-free bronze construction and backflow prevention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before installing or replacing this valve. Use the hex body to torque the fitting with an appropriately sized wrench — do not grip on the poppet end or seal area. Verify correct flow direction before final makeup, as check valves are directional and will not function if installed in reverse.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Lead-free unleaded bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoppet Material\u003c\/strong\u003e: Acetal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile (Buna-N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 100E Enviro\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLOMATIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4201e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLOMATIC","offers":[{"title":"Default Title","offer_id":51467379343666,"sku":"4201E","price":78.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946207.jpg?v=1783902856","url":"https:\/\/voomisupply.com\/products\/flomatic-4201e-1-inch-lead-free-bronze-check-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
