Built with a brass body, it provides precise throttling control through an adjustable needle mechanism. The valve features a tube-to-NPT connection configuration with a 1\/4 inch tube outside diameter and a 1\/8 inch NPT inlet. It is well-suited for use in compressed air lines, pneumatic circuits, and instrumentation systems where controlled flow adjustment is required. Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals are the typical installers for this class of valve.\u003c\/p\u003e\n\u003cp\u003eThis valve is commonly installed in light industrial and commercial pneumatic control applications. It is used in air-actuated systems, panel-mount assemblies, and compressed air distribution lines where fine flow adjustment is needed. The tube-to-NPT design allows direct connection to standard NPT-threaded ports while accommodating tubing on the opposing side, making it adaptable to a range of pneumatic plumbing configurations. At 0.11 pounds, it is compact and lightweight for easy inline installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNeedle valve design allows precise manual adjustment of airflow rate\u003c\/li\u003e\n  \u003cli\u003eBrass body construction offers durability and resistance to corrosion in pneumatic service\u003c\/li\u003e\n  \u003cli\u003eTube x NPT connection accommodates 1\/4 inch OD tubing with a 1\/8 inch NPT port\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.11 pounds for use in space-constrained installations\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single-piece unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for pneumatic flow control applications using 1\/4 inch OD tubing and 1\/8 inch NPT-threaded ports in compressed air systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed pipefitters, pneumatic system technicians, or industrial mechanical contractors. Depressurize and isolate the pneumatic circuit completely before removing or installing any flow control valve. Use appropriate thread sealant on NPT connections per applicable plumbing and mechanical codes. Avoid overtightening the needle adjustment to prevent damage to the internal seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Needle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube x NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/8 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: NORGREN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12VB00418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORGREN","offers":[{"title":"Default Title","offer_id":51691360125234,"sku":"12VB00418","price":146.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93dd47cc03fbae3490e7d7088e9a6ee0.jpg?v=1788283773","url":"https:\/\/voomisupply.com\/products\/norgren-12vb00418-needle-air-flow-control-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
