More Information
Summary:An arrangement for controlling the flow rate through a hydraulic valve, the arrangement comprising a control device having a first range of positions for providing a first range of flow rates through the hydraulic valve, a second range of positions for providing a second range of flow rates through the hydraulic valve, and a neutral position for providing substantially no flow through the hydraulic valve, wherein the relationship between the first range of flow rates through the hydraulic valve and the first range of positions of the control device is substantially linear having a first ratio and the relationship between the second range of flow rates through the hydraulic valve and the second range of positions of the control device is substantially linear having a second ratio.
