Rated to 3000 psi maximum working pressure, this valve accepts 1\/2 inch compression fittings on both the inlet and outlet ends, making it a reliable choice for instrumentation, hydraulic, and process lines where leak-free shutoff and fine metering are required. Licensed plumbers, pipefitters, and instrumentation technicians install this type of valve in applications where standard ball or gate valves lack the throttling precision the job demands. At 0.7 pounds, it is compact enough for tight panel or manifold installations.\u003c\/p\u003e\u003cp\u003eThis valve is suited for straight-line installation in compressed air, hydraulic fluid, refrigerant, water, and compatible gas service lines operating up to 3000 psi. The compression-by-compression end configuration allows connection to existing tubing runs without the need for additional adapters in most standard 1\/2 inch tube installations. It is commonly found in commercial and industrial process control panels, test benches, and HVAC\/R equipment service ports where incremental flow adjustment is necessary.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum working pressure of 3000 psi for demanding high-pressure service\u003c\/li\u003e\n\u003cli\u003eStraight body style for in-line installation without directional change\u003c\/li\u003e\n\u003cli\u003eCompression x compression end connections on both ports for secure, leak-resistant tube attachment\u003c\/li\u003e\n\u003cli\u003e1\/2 inch pipe size fits standard half-inch tubing runs\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.7 pounds for use in confined spaces or instrument panels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style straight needle valve for use in 1\/2 inch compression tube systems rated up to 3000 psi. No specific compatible model numbers or replacement part numbers were provided in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or instrumentation technician familiar with high-pressure tubing systems. Depressurize and isolate the line completely before removing any existing fitting or valve. Compression fittings must be seated properly and tightened to the fitting manufacturer specification to prevent leaks under pressure. Follow all applicable local codes and ASME or system-specific pressure rating guidelines when integrating this valve into a pressurized circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 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: 3000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: 8Z-V8LN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542178660658,"sku":"8Z-V8LN-B","price":273.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e8fd7741256ebf40283103d5a4be924_46219ae9-6dbe-4678-a902-4f501330d7d9.jpg?v=1785894311","url":"https:\/\/voomisupply.com\/products\/parker-8z-v8ln-b-straight-needle-valve-1-2-in-compression","provider":"Voomi Supply","version":"1.0","type":"link"}
