In the hydraulic steering system, the steering orbitrol valve is responsible for distributing the flow and pressure of the hydraulic oil to the steering jacks. The technology of making this valve was available to a limited number of countries before 2018, when Aradfan Hydraulic Naein Company localized this product. Currently, the steering orbitrol valve produced by Aradfan Hydraulic Naein Company is used for a variety of heavy machinery, including agricultural and road construction machinery.
