Built with a brass body and brass trim, it connects via female NPT threads on both ends and operates with a padlock-style handle for lockout-tagout compliance. The valve is rated to 250 psi working pressure and handles temperatures from 0 degrees F to 350 degrees F. Seating and seal surfaces use reinforced polytetrafluoroethylene (PTFE), which resists chemical degradation and provides reliable shutoff across a wide range of media. Licensed plumbers and pipefitters are the typical installers for this type of valve.\u003c\/p\u003e\u003cp\u003eThis valve is suited for residential and light commercial plumbing, HVAC hydronic piping, compressed air lines, and other low-to-medium pressure fluid handling systems where a vented ball valve is required. The FNPT x FNPT end configuration fits standard threaded pipe runs in 1\/4 inch nominal pipe size. The padlock handle feature makes it appropriate for systems requiring lockout-tagout procedures during service or maintenance intervals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVented ball design allows pressure bleed-off between handle positions\u003c\/li\u003e\n\u003cli\u003eBrass body and brass trim for corrosion resistance in water and air service\u003c\/li\u003e\n\u003cli\u003eReinforced PTFE seats and seals for chemical compatibility and long service life\u003c\/li\u003e\n\u003cli\u003e250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 0 degrees F to 350 degrees F\u003c\/li\u003e\n\u003cli\u003ePadlock handle supports lockout-tagout compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation valve for standard 1\/4 inch FNPT threaded pipe systems in plumbing, HVAC hydronic, and compressed air applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC and local mechanical code requirements. Depressurize and drain the affected line before removing or installing any threaded valve. Apply thread sealant or PTFE tape to male threads before making up the connection and tighten to hand-tight plus the appropriate additional turns per pipe material without over-torquing the brass body. Verify no leaks under system pressure before returning the line to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Standard Ball Valve, Vented\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: Reinforced Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Reinforced Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Padlock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F (-17 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 350 degrees F (176 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XVVP500P-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539061113138,"sku":"XVVP500P-4","price":71.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/876cd89b68cd9ba64f7a8a9983ad0b52.jpg?v=1785833986","url":"https:\/\/voomisupply.com\/products\/parker-xvvp500p-4-vented-ball-valve-1-4-inch-fnpt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
