I. Working Principle The hydraulic oil is pressurized by a vane pump and then passes through a filter, a flameproof electromagnetic reversing valve, a throttle valve, a pilot-operated check valve, and a balance valve to enter the lower end of the hydraulic cylinder. This causes the piston of the hydraulic cylinder to move upward, thereby […]
