The body and spring are constructed from polytetrafluoroethylene (PTFE), making it highly resistant to corrosive media and compatible with a wide range of process fluids. It connects via female NPT (FNPT) threads on both ends and fits a 1-inch pipe. With a crack pressure range of 0.25 to 0.75 psi and a Cv rating of 14.0, this valve suits low-differential-pressure applications where precise cracking threshold and adequate flow capacity are both required. Licensed plumbers, pipefitters, and process technicians typically install this valve in industrial, commercial, and chemical handling lines.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for inline installations in process piping, fluid transfer systems, and chemical distribution lines where backflow prevention is critical. The PTFE construction makes it appropriate for use with aggressive or high-purity fluids that would degrade metal or elastomeric components. It operates across a temperature range of -32 degrees F to 130 degrees F, which covers most above-ground process and utility piping scenarios. Its FNPT x FNPT end connections allow direct threaded installation into standard NPT piping without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE body and spring construction for broad chemical compatibility and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1-inch FNPT x FNPT end connections for standard threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003eLow crack pressure of 0.25 to 0.75 psi suits low-differential-pressure systems\u003c\/li\u003e\n  \u003cli\u003eCv rating of 14.0 supports adequate flow capacity for 1-inch line applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -32 degrees F to 130 degrees F\u003c\/li\u003e\n  \u003cli\u003eInline valve orientation simplifies installation in existing piping runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline check valve replacement for 1-inch FNPT threaded piping systems requiring PTFE wetted components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter following applicable IPC or ASME B31 piping codes. Shut off system pressure and drain the line completely before removing an existing valve or installing this unit. Apply thread sealant rated for the process fluid to the FNPT connections and do not overtighten, as PTFE threads can gall or crack under excessive torque. Verify flow direction markings on the valve body before final assembly to ensure proper check valve orientation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 0.25 to 0.75 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 14.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -32 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 130 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CV-1-111616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542251864370,"sku":"CV-1-111616","price":2459.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07bc41a83082e1b7ae1e8b64bd6501a8_29c7b15c-3c3c-45d4-8203-f3a5389e8fe4.jpg?v=1785896403","url":"https:\/\/voomisupply.com\/products\/parker-cv-1-111616-inline-check-valve-1-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
