Brief introduction:

    Hitachi EX200C01 series of cartridge type hydraulic pressure relief valve blocks the returning circuit of system pressure, to increase the pressure in system pipe line by the sealing loop of the spool and piston, the hydraulic pressure relief valve setting must be in the prescribed amount of oil (usually far less than the main pump oil volume ). Therefore, if the main relief valve set pressure can be re-set to higher than overload relief valve set pressure.
    The fail of establishing pressure for cartridge type hydraulic pressure relief valve is the reason to Hitachi EX200 Excavator slow movement, the pressure is low, the main relief of the equipment is likely to be the cause of the failure culprit.
    As a safety valve located on the main relief valves in the distributor and its role is to limit the maximum pressure of the entire hydraulic system is to protect the entire system and not damage.

    The pressure of entire hydraulic system will lead too low if the spring broken or too low presetting pressing in valve, the main pump pressure oil will not be able to promote the implementation of the components work properly, there will be slow to move the Excavator no action, main relief valve should be checked and replace or adjusted.
