Built with a brass body and nitrile seals, it handles a maximum working pressure of 2000 psi and a maximum flow rate of 5 GPM. The 1\/4-18 NPT threaded inlet makes it straightforward to integrate into standard hydraulic lines. At 2.63 inches overall length and 0.4 pounds, this compact valve fits in tight plumbing configurations without adding significant bulk. Hydraulic technicians and fluid power specialists install this valve as part of directional or flow-control assemblies in industrial and mobile hydraulic systems.\u003c\/p\u003e\n\u003cp\u003eThe C400B suits residential and light commercial hydraulic applications where one-way flow regulation is required. Its brass construction holds up well in systems carrying standard hydraulic fluid, and the nitrile seal material is compatible with petroleum-based hydraulic oils. Typical installations include hydraulic power units, cylinder circuits, and auxiliary control lines where controlled single-direction flow is needed. The 1\/4-inch NPT connection is a common size across a wide range of hydraulic manifolds, fittings, and ported blocks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-way flow regulation up to 5 GPM\u003c\/li\u003e\n  \u003cli\u003eRated for up to 2000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPT threaded connection for standard hydraulic plumbing\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for durability in hydraulic environments\u003c\/li\u003e\n  \u003cli\u003eNitrile seals compatible with petroleum-based hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eCompact 2.63-inch overall length for space-constrained installations\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 hydraulic control circuits using 1\/4-inch NPT connections rated to 2000 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed hydraulic technician or fluid power specialist. Always depressurize and bleed the hydraulic system fully before removing or installing any valve. Use appropriate thread sealant rated for hydraulic service on NPT connections, and avoid over-tightening brass-bodied fittings. Follow applicable industry standards and equipment manufacturer guidelines for torque and system commissioning procedures.\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: 2000 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\u003eFlow Regulation Type\u003c\/strong\u003e: One-Way\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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\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: C400B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540012302642,"sku":"C400B","price":72.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eac8f54db9dd96235ba87f8bc1117a2_57487971-b3bf-40ab-85ea-e11f4b7ca7e9.jpg?v=1785845379","url":"https:\/\/voomisupply.com\/products\/parker-c400b-hydraulic-control-valve-5-gpm-2000-psi-1-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
