The set pressure of the PC200 – 7 main relief valve is typically in the range of 320 – 350 bar. This value is carefully determined based on the design and strength of the hydraulic components in the excavator. Por ejemplo, if the pressure in the system rises above this set point during heavy – duty operations like lifting a very heavy load, the relief valve will activate to prevent any potential damage.

Pressure Override Capacity

The valve can handle a certain amount of pressure override. En el PC200 – 7, it is usually designed to tolerate a short – term pressure spike up to around 380 – 400 bar without immediate failure. This provides a safety margin to account for sudden changes in the hydraulic system, such as the impact when the bucket hits a hard object during excavation.
