Built with a polytetrafluoroethylene (PTFE) body and PTFE spring, this valve delivers strong chemical resistance across a wide range of media. Rated at 120 WOG (Water, Oil, Gas), it is sized for 3\/4-inch pipe with PARFLARE x PARFLARE end connections and carries a Cv rating of 4.100, indicating moderate flow capacity for its pipe size. It is a compact, lightweight component suited for licensed plumbers, HVAC technicians, and industrial pipefitters working on systems that require reliable non-return flow control.\u003c\/p\u003e\n\u003cp\u003eThis check valve is used in inline piping applications where backflow prevention is required without reliance on an external power source or actuator. The PARFLARE x PARFLARE connection style makes it compatible with flared-fitting piping assemblies, commonly found in refrigeration, HVAC, and fluid-handling systems. At 0.35 pounds, it is a lightweight option for installations in tight mechanical spaces or in-line runs where minimizing added load matters. Residential and light commercial installations are both typical use cases for this valve type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE body and spring construction provides excellent chemical resistance\u003c\/li\u003e\n  \u003cli\u003ePARFLARE x PARFLARE end connections for secure flared-fitting integration\u003c\/li\u003e\n  \u003cli\u003e120 WOG pressure rating supports water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eCv rating of 4.100 supports consistent flow performance at 3\/4-inch pipe size\u003c\/li\u003e\n  \u003cli\u003eInline design allows direct installation into existing piping runs\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.35 pounds for easy handling and installation in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline check valve for 3\/4-inch pipe systems using PARFLARE x PARFLARE flared end connections, rated for water, oil, and gas service up to 120 WOG.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC or refrigeration technician. Shut off system pressure and depressurize the line completely before removing any existing valve or fitting. Verify flow direction markings on the valve body and install accordingly, as reversing orientation will block intended flow. Ensure flare connections are properly formed and seated to prevent leaks before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: PARFLARE x PARFLARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 120 WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 4.100\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\u003eWeight\u003c\/strong\u003e: 0.35 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-1-661212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538931581234,"sku":"CV-1-661212","price":922.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc3130d22d77eea9e61628ce3da80c7.jpg?v=1785830060","url":"https:\/\/voomisupply.com\/products\/parker-cv-1-661212-inline-check-valve-3-4-inch-ptfe","provider":"Voomi Supply","version":"1.0","type":"link"}
