GVO YT22V00019F1 Balance Valve Pressure Relief Valve Control Valve for SK70SR-2 SK75-8 SK80CS-2

Key attributes

Reliable Overload Protection
When system pressure exceeds the safe threshold due to sudden shocks or excessive loads, the valve opens instantly to return excess oil to the tank. This effectively prevents damage to expensive components such as the main pump, cylinders, and hydraulic lines – serving as a critical safeguard for the machine's "heart."
