Özet

Mobile direction control valves are hydraulic system components which transfer the hydraulic oil to the accelerator to control the system. These components are mostly used in tractors, forklifts, and backhoe loaders. Forward or backward movement of the valve spools determines the motion direction and speed of the equipment. However, in some cases, using the flow control valves is an effective way to determine the speed of movement. For a tractor with multiple actuators, direction control valves with priority flow control should be used to supply low flow rate without load dependency to the actuator. In this paper, priority flow control valve is modeled using one-dimensional simulation technique and simulation results are validated with the experimental results.
