Hydraulic drive system to achieve flow control in which way what are the key components used in the

Throttle valve, speed control valve; throttle valve. Hydraulic drive system is applied to engineering machinery and other fields of the system, the realization of the flow control in the way there are throttle valves, speed control valves, the key components used are throttle valves. Hydraulic drive system is a hydraulic pump, hydraulic pump to convert mechanical energy into liquid pressure energy, hydraulic control valves and hydraulic accessories to control the pressure, flow and flow direction of the hydraulic medium, the output of the hydraulic pump pressure energy to the actuating element, the actuating element will be converted to mechanical energy of the liquid pressure energy, in order to complete the required action.
