Built with a brass body and a polytetrafluoroethylene (PTFE) seal, this valve handles working pressures up to 3,000 psi, making it suitable for demanding hydraulic, pneumatic, and instrumentation applications. The 1\/8 inch FNPT x FNPT end connections allow direct inline installation into standard pipe assemblies. The round handle provides manual flow adjustment. Licensed plumbers, HVAC technicians, and instrumentation technicians are the typical installers for this type of valve in both commercial and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for use in compressed gas lines, hydraulic instrumentation circuits, fuel systems, and other high-pressure service applications requiring a compact, inline shutoff or throttling point. The straight body configuration simplifies in-line plumbing where flow direction does not need to change. At 1\/8 inch pipe size, it fits small-bore piping commonly found in control panels, test benches, and instrument manifolds. It is packaged individually and intended for professional installation in systems where precise flow metering or positive shutoff is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight-pattern body keeps flow path in a single direction for simplified inline installation\u003c\/li\u003e\n  \u003cli\u003eBrass body construction offers corrosion resistance in water, air, and compatible fluid services\u003c\/li\u003e\n  \u003cli\u003ePTFE seal provides chemical compatibility and low-friction stem operation\u003c\/li\u003e\n  \u003cli\u003eRated to 3,000 psi maximum working pressure for high-pressure service\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch FNPT x FNPT connections for direct threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003eRound handle allows manual flow control and throttling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation needle valve for 1\/8 inch FNPT threaded pipe systems in high-pressure hydraulic, pneumatic, and instrumentation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified instrumentation technician in accordance with applicable local codes and the system pressure ratings. Depressurize and isolate the line completely before removing or installing any needle valve. Apply thread sealant or PTFE tape to male threads per standard practice, and do not overtighten threaded connections in brass-bodied fittings. Verify that the valve flow rating and seal material are compatible with the specific fluid or gas in the system before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/8 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\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 3.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Round\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: 2F-V4LN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542376775986,"sku":"2F-V4LN-B","price":350.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61912aa0518bb1832b70826f889fb239.jpg?v=1785899000","url":"https:\/\/voomisupply.com\/products\/parker-2f-v4ln-b-needle-valve-1-8-inch-fnpt-brass-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
