Built with a brass body, the valve handles a maximum flow rate of 5 GPM through a 1\/4-18 NPT inlet. It measures 2.63 inches in overall length and features a knob-style handle for manual adjustment. Nitrile seals provide reliable performance across a range of hydraulic fluids. At 0.5 pounds, the compact form factor suits installations where space and weight are considerations. Licensed hydraulic system technicians and industrial maintenance professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe F400B is suited for use in light-duty hydraulic circuits where manual flow control is required. Its 1\/4-inch NPT thread makes it compatible with standard hydraulic plumbing in both stationary and mobile equipment applications. Typical installation scenarios include machine tool hydraulics, small power units, and hydraulic test benches where precise manual throttling of fluid flow is needed at moderate pressures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum working pressure of 2,000 psi for use in moderate-pressure hydraulic circuits\u003c\/li\u003e\n  \u003cli\u003e5 GPM maximum flow rate supports light to medium hydraulic system demands\u003c\/li\u003e\n  \u003cli\u003eBrass body construction offers corrosion resistance in hydraulic fluid environments\u003c\/li\u003e\n  \u003cli\u003eNitrile seals compatible with common petroleum-based hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eKnob handle allows tool-free manual flow adjustment\u003c\/li\u003e\n  \u003cli\u003eCompact 2.63-inch overall length fits tight plumbing layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit valve for hydraulic circuits using 1\/4-18 NPT threaded connections and operating within a 5 GPM and 2,000 psi envelope.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic system technician or industrial maintenance professional. Depressurize and de-energize the hydraulic system fully before removing or installing any valve. Use appropriate thread sealant rated for hydraulic service on NPT connections and verify torque to fitting manufacturer specifications. Confirm system pressure and flow ratings do not exceed the valve's 2,000 psi and 5 GPM limits before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 5 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Knob\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Hydraulic Control\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: F400B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540333756722,"sku":"F400B","price":103.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3048816b85e23def16dfb0ba36f10351_61817b32-5d17-471f-a2b0-fabb372ec503.jpg?v=1785852431","url":"https:\/\/voomisupply.com\/products\/parker-f400b-hydraulic-control-valve-5-gpm-2000-psi-1-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
