This valve plays a critical role in the hydraulic system by limiting pressure and preventing overload, acting as a "safety valve" to protect the entire system.
Pressure Setting: Establishes a maximum operating pressure limit for the system.
Overload Protection: When system pressure exceeds the preset value due to heavy loads or shocks, the valve opens rapidly to divert excess hydraulic oil back to the tank. This effectively prevents high pressure from damaging expensive components such as the hydraulic pump, control valves, cylinders, and lines.
Pressure Balancing: Helps balance pressure within the hydraulic system, ensuring stable and reliable operation.
