Brand New Safety Relief Valve LJ00800 - Replacement for CX130, CX160, and CX180 Excavators
The LJ00800 relief valve is used to control system pressure and protect the safe operation of the hydraulic circuit. When the system pressure exceeds the set value, the valve automatically opens to release pressure, preventing overload damage to the hydraulic pump and actuators.
High-Precision Machining: CNC manufactured, ensuring stable and controllable pressure. High-Strength Material: Alloy steel structure, wear-resistant and impact-resistant. OEM Standard: Size matching, ready to use. System Protection: Stabilizes peak pressure and prevents overload damage.
