Built with a polytetrafluoroethylene (PTFE) body and PTFE spring, this valve handles working pressures up to 120 WOG (water, oil, gas). The PARFLARE x PARFLARE end connections suit flared-tube installations common in HVAC and refrigeration lines. With a Cv rating of 1.110, it provides predictable flow characteristics for 3\/8 inch pipe sizing. Licensed HVAC technicians and refrigeration service professionals are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for inline installation in refrigeration circuits, HVAC refrigerant lines, and fluid control systems where backflow prevention is required. The 3\/8 inch pipe size and PARFLARE fittings on both ends make it a direct fit for flared-tube assemblies in residential and light commercial systems. Its PTFE construction offers broad chemical compatibility, making it appropriate for use with common refrigerants and hydraulic media where metal body valves may not be preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE body and spring construction for broad chemical and refrigerant compatibility\u003c\/li\u003e\n  \u003cli\u003ePARFLARE x PARFLARE end connections for flared-tube inline installation\u003c\/li\u003e\n  \u003cli\u003e120 WOG pressure rating for reliable service in fluid and refrigerant applications\u003c\/li\u003e\n  \u003cli\u003eCv rating of 1.110 provides consistent, predictable flow performance\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch pipe size suits standard HVAC and refrigeration line sizing\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 3\/8 inch PARFLARE flared-tube connections in HVAC, refrigeration, and fluid control systems rated at or below 120 WOG.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified refrigeration mechanic. Recover and isolate refrigerant or depressurize the system fully before removing any existing valve. Verify that flow direction marked on the valve body aligns with the intended system flow path before tightening PARFLARE connections. Follow applicable mechanical codes and manufacturer torque guidelines for flare fittings to avoid joint failure.\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: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: PARFLARE x PARFLARE\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: 1.110\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: 0.2 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-1-6666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542272377138,"sku":"CV-1-6666","price":484.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc3130d22d77eea9e61628ce3da80c7_942bdd29-0cf3-4994-85e7-bd97d4926633.jpg?v=1785897011","url":"https:\/\/voomisupply.com\/products\/parker-cv-1-6666-inline-check-valve-3-8-in-parflare-ptfe","provider":"Voomi Supply","version":"1.0","type":"link"}
