What occurs when the Hydraulic Pressure Bypass Valve is opened?

When the Hydraulic Pressure Bypass Valve is opened, the hydraulic fluid is rerouted back to the reservoir. This action is typically a safety feature designed to protect the hydraulic system from overpressure. When the bypass valve is engaged, excess pressure can be released, preventing potential damage to components within the hydraulic system. As a result, the system can continue to operate under normal conditions without excessive pressure buildup. This rerouting ensures that essential hydraulic functions can still be performed safely, albeit at a lower efficient level, rather than ceasing entirely or increasing pressure, which might lead to failures or leaks. Understanding this function is critical for maintenance and troubleshooting within hydraulic systems.
