Abstract: Introduces working principle and property behavior of digital multifunctional electrohydaulic valve. In light of the application and oil dispatching requirement of the valve in microcomputer oil dispatching system, puts forward methods using preset control point of integrated flow and introducing correction factor into transmitting control algorithm for the purpose of ensuring safety, high efficiency, small momentum and high precision control of oil dispatching with microcomputer. Using digital multifunctional electrohydraulic valve can bring the superiority of microcomputer control software into full play. It is valuable for popularization and application.
