The rated operating pressure of the CAT 307.5 main control valve is typically around 250 - 300 bar (25 - 30 MPa). This pressure rating is sufficient to drive the hydraulic components of the 307.5 excavator for normal operations.
For the CAT 310 excavator main valve, the rated pressure is usually higher, in the range of 300 - 350 bar (30 - 35 MPa), due to the larger size and more powerful functions of the 310 model.
Maximum Pressure:
The CAT 307.5 main control valve can withstand a maximum pressure of around 350 bar (35 MPa) for short periods. This additional pressure capacity allows it to handle sudden peak loads during the excavator's operation.
The CAT 310 excavator main valve can handle a maximum pressure of up to 400 bar (40 MPa) or more for short durations to cope with extreme operating conditions.
