Built with a 316 stainless steel body and a polytetrafluoroethylene (PTFE) seal, it handles working pressures up to 5,000 psi. The round handle provides manual throttling control, and the male NPT connections on both ends allow for straightforward inline installation. At 1.88 inches overall length and 3.06 inches overall height, this valve fits into compact plumbing and instrumentation assemblies. Licensed plumbers, pipefitters, and instrumentation technicians install this valve in process lines, test rigs, and hydraulic systems where reliable shutoff and flow metering are required.\u003c\/p\u003e\u003cp\u003eThis valve is suited for residential and commercial applications involving high-pressure lines where corrosion resistance and a reliable seal are priorities. The 1\/4 inch pipe size and MNPT x MNPT end configuration make it a common choice for instrument manifolds, sample lines, chemical injection points, and hydraulic test panels. The 316 stainless steel body provides resistance to corrosive media, and the PTFE seal maintains integrity across a wide range of fluid and gas types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum working pressure of 5,000 psi suitable for high-pressure applications\u003c\/li\u003e\n\u003cli\u003e316 stainless steel body for corrosion resistance in aggressive media\u003c\/li\u003e\n\u003cli\u003ePTFE seal compatible with a broad range of fluids and gases\u003c\/li\u003e\n\u003cli\u003eMNPT x MNPT end connections for standard inline installation\u003c\/li\u003e\n\u003cli\u003eRound handle design for manual flow throttling and shutoff\u003c\/li\u003e\n\u003cli\u003eCompact overall dimensions: 1.88 inches OAL and 3.06 inches OAH\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation needle valve for 1\/4 inch MNPT high-pressure instrumentation and process piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or ASME B31.3 for process piping. Depressurize and isolate the line fully before removing any existing valve or making connections. Apply appropriate thread sealant rated for the system media and pressure to the MNPT threads before installation. Do not exceed the rated working pressure of 5,000 psi.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: MNPT x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.88 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\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 4M-V4LN-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540146684210,"sku":"4M-V4LN-SS","price":165.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7596502f42e3952cddc89b909139b1a.jpg?v=1785847065","url":"https:\/\/voomisupply.com\/products\/parker-4m-v4ln-ss-needle-valve-1-4-inch-mnpt-stainless-5000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
