Rated Pressure: The rated operating pressure of this main control valve is typically around 250 – 300 バー (25 – 30 MPa). This pressure rating is in line with the hydraulic system's requirements of the DOOSAN DX75-5B excavator, allowing it to handle the pressures necessary for the excavator's normal operations.
Maximum Pressure: The maximum pressure that the valve can withstand for short periods is usually higher than the rated pressure, often reaching up to 350 バー (35 MPa) or more. This additional pressure capacity enables the valve to handle sudden peak loads during the excavator's operation, ensuring the reliability and durability of the hydraulic system.
