With \u003cstrong\u003e9.76 cubic inches of displacement\u003c\/strong\u003e, this valve meters hydraulic fluid to the steering cylinder as the steering wheel is turned, giving the driver consistent control without a mechanical steering connection to the axle.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eOrbital valve displacement is an important part of building a hydraulic steering system. Valve displacement works together with steering cylinder volume to determine how many steering wheel turns are required to move from lock to lock. A larger displacement moves more fluid per steering wheel revolution for quicker steering, while a smaller displacement moves less fluid for slower response and finer control.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe FHV-RR160 is a universal option for rock crawlers, trail rigs, buggies, and custom off-road vehicles running full hydraulic steering.
