Rated Pressure: The rated operating pressure of this main control valve is typically around 350 – 400 bar (35 – 40 MPa). This pressure rating is in line with the high-pressure requirements of the hydraulic systems of the 349GC and 350 excavators, enabling it to handle the rigorous demands of heavy-duty 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 450 bar (45 MPa) or more. This additional pressure capacity allows the valve to cope with sudden peak loads during the excavators' operation, safeguarding the reliability and durability of the hydraulic system.
