Selection of flow hydraulic directional control valves

According to the working condition of the hydraulic system and the characteristics of the dg4v-3 flow control valve to select the flow hydraulic directional control valves, in order to control the velocity of actuators.For example, the implementation of component requires for speed stability, but does not produce crawling, dg4v-3-6c speed hydraulic directional control valves should be selected. In the selection of the specifications of the hydraulic directional control valve, should pay attention to the dg4v-3-6c minimum stable flow rate valve, should meet the requirements of the minimum speed of the actuator, that is, the minimum stable flow rate should be less than the minimum flow required for execution components; if the flow stability requirements are particularly high, or for the case of micro feed, should choose the dg4v-3-2a temperature compensated type valve. In short, whether the choice of the dg4v-3-2c hydraulic directional control valve is correct or not has a great effect on the success or failure of the system.
As a hydraulic designer, should have a more comprehensive understanding of the production of dg4v-3-2a hydraulic directional control valves, in particular, the performance of various hydraulic directional control valves, the replacement of new and old products and replacement. Should also often go to the scene to understand the work of the dg4v-3 hydraulic directional control valve, the only way to achieve the correct and reasonable choice of hydraulic directional control valve.
