Product Specification

LQ22V00002F1 Pressure Relief Valve Rotating Motor Relief Valve SK250LC-6E SK260-8 SK485LC-9 SK485-9 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SK250LC-6E SK260-8 SK485LC-9 SK485-9 excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.

This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction

This main relief valve is suitable for the main control distribution valves of SK250LC-6E, SK260-8, SK485LC-9, and SK485-9 excavators. It is a crucial main pressure control valve in the entire hydraulic system of the machine and is commonly known as the main gun in the industry. It is mainly responsible for limiting the hydraulic main circuit pressure and providing overload relief protection. The relief valve directly controls the maximum working pressure of the entire machine, determines the digging force, rotation torque, and power output , and ensures the smoothness of compound actions.

The valve body is forged from high-strength alloy steel as a whole and undergoes multiple heat treatment processes, balancing hardness and toughness. It has outstanding resistance to high-pressure impact and deformation, and can withstand large-flow hydraulic impacts of medium-sized excavators. The valve body does not deform easily even under long-term heavy-load operation. The valve core is manufactured using a high-precision mirror grinding process, with strict control of the clearance between the valve core and the valve sleeve. An internal high-toughness anti-fatigue pressure regulating spring is assembled, along with a high-pressure-resistant and aging-resistant sealing component. In harsh working conditions such as mines and earthwork, the valve core responds quickly, discharges pressure, and resets smoothly, effectively suppressing internal leakage under high-pressure conditions. Even after the oil temperature rises, it can still maintain stable pressure regulation performance and can well adapt to the construction environment where the equipment operates continuously at high intensity.
