The valve uses a screw adjustment mechanism to provide precise, repeatable flow control in either direction, making it suitable for applications where bidirectional flow management is required. The body is constructed from nickel-plated brass for corrosion resistance, and the internal sealing is handled by a Buna Nitrile O-ring. The 3\/8-inch tube OD connection and 1\/4-inch male thread fitting make this valve a common choice in compressed air lines and pneumatic control circuits. Licensed pneumatic system technicians and industrial maintenance professionals are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for use in compressed air distribution systems, pneumatic actuator circuits, and automated control applications where airflow must be throttled or metered in both directions. The 3\/8-inch tube OD size is a standard fit for light-to-medium duty pneumatic lines found in industrial, commercial, and trade shop environments. It is appropriate for use where a compact, inline flow control is needed without a dedicated directional preference.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBi-directional flow control allows use in either flow direction without a dedicated inlet or outlet\u003c\/li\u003e\n  \u003cli\u003eScrew adjustment provides precise manual control of airflow rate\u003c\/li\u003e\n  \u003cli\u003eNickel-plated brass body resists corrosion in compressed air environments\u003c\/li\u003e\n  \u003cli\u003eBuna Nitrile O-ring provides reliable sealing across a broad temperature range\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch tube OD and 1\/4-inch male universal thread for straightforward installation into standard pneumatic fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation flow control valve for pneumatic systems using 3\/8-inch OD tubing and 1\/4-inch male thread connections with a universal thread type.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic system safety practices. Depressurize the air line completely before removing or installing any fittings or valves. Apply appropriate thread sealant compatible with compressed air service to the male threads before installation, and do not overtighten the fitting. Confirm the screw adjustment is set to the desired flow rate before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Bi-Directional Screw Adjusted Flow Control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Nickel-Plated Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Buna Nitrile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141603\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: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2556238166PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51747165602098,"sku":"2556238166PRO","price":38.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e473f8b2ab742c5d05bcdf276852dc7d.jpg?v=1788876959","url":"https:\/\/voomisupply.com\/products\/pro-source-2556238166pro-air-flow-control-valve-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
