Built with a 316 stainless steel body and a polytetrafluoroethylene (PTFE) seal, this valve delivers corrosion resistance and chemical compatibility across demanding service environments. It accepts 1\/4-inch compression fittings on both ends and is rated to 5,000 psi maximum working pressure. The round handle provides manual throttling control and is well-suited for instrumentation, process, and industrial plumbing applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis valve is intended for use in straight-line installations where fine flow metering or shutoff is required. The compression-by-compression end connections make it compatible with tubing runs in process instrumentation panels, hydraulic test rigs, and high-pressure fluid lines. The stainless steel construction handles corrosive media and wash-down environments. Its compact overall dimensions of 2.3 inches overall length and 3.06 inches overall height allow installation in space-constrained assemblies without sacrificing pressure rating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e316 stainless steel body for corrosion resistance in harsh or corrosive service\u003c\/li\u003e\n\u003cli\u003ePTFE seal provides chemical compatibility with a wide range of process fluids and gases\u003c\/li\u003e\n\u003cli\u003eRated to 5,000 psi maximum working pressure for high-pressure applications\u003c\/li\u003e\n\u003cli\u003eStraight-pattern configuration for in-line installation\u003c\/li\u003e\n\u003cli\u003e1\/4-inch compression x compression end connections for tool-free tube attachment\u003c\/li\u003e\n\u003cli\u003eRound handle for controlled manual flow adjustment and shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation needle valve for 1\/4-inch compression tubing systems requiring high-pressure flow control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Depressurize and isolate the system fully before removing any existing valve or fitting. Ensure tubing ends are cut square, deburred, and fully seated into the compression fittings before tightening. Follow applicable plumbing codes and the fitting manufacturer torque guidance for compression connections.\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: Compression x Compression\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\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\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: 4Z-V4LN-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540210614578,"sku":"4Z-V4LN-SS","price":184.32,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc17815afa13f1439b948963a295df25.jpg?v=1785848936","url":"https:\/\/voomisupply.com\/products\/parker-4z-v4ln-ss-needle-valve-1-4-in-compression-ss-body","provider":"Voomi Supply","version":"1.0","type":"link"}
