Applicable excavator main relief valve 723-30-90101

The hydraulic cylinder is an important actuator of the hydraulic system, which can use the oil provided by the hydraulic pump to produce its own movement through the gas or liquid pressure inside the actuator. Changes in the internal volume of the hydraulic cylinder can be fed back to the hydraulic pressure through the oil supplied by the hydraulic pump
In the pump, thus realizing the automatic adaptation of the hydraulic pump.
The working principle of the hydraulic motor is basically the same as that of the hydraulic cylinder, except that the high-pressure oil of the hydraulic system is pushed through the flow of a relatively small internal turbine type and other components to produce a rotating or moving force.
The pressure control valve is an important component in the hydraulic system that can limit the pressure, and its main function is to limit the maximum pressure of the hydraulic pressure inside the system to ensure that the system will not be damaged due to excessive pressure.
The flow control valve is a component used to regulate the flow of oil, which can precisely control the speed of the hydraulic cylinder to make the movement of the hydraulic cylinder more stable.
Direction control valve is an important component in the hydraulic system to adjust the direction of mechanical movement, it can adjust the flow of hydraulic oil, so as to achieve various movements in the hydraulic system.
