What are the conditions in the hydraulic system with the imported throttle valve? What is the difference between the throttle valve and the outlet valve?
3, import throttle speed regulation, unlike the export throttle speed control, can bear negative load, so the movement is less smooth. Can be added by back pressure valve to solveNeed to speed sensitive, quick response, with import throttle. If the action is smooth, shock resistance load, with oil return throttling
2., import throttle speed control, easy to use pressure relay to achieve pressure control;
1. pairs of single rod hydraulic cylinder, import throttle speed into the non rod cavity, you can get more speed than the oil back throttling speed
