Presiune nominală: The rated operating pressure of this main control valve is typically around 250 – 300 bar (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.
Presiune maximă: The maximum pressure that the valve can withstand for short periods is usually higher than the rated pressure, Adesea ajungând până la 350 bar (35 MPA) sau mai mult. This additional pressure capacity enables the valve to handle sudden peak loads during the excavator's operation, asigurând fiabilitatea și durabilitatea sistemului hidraulic.
