Product Description

The GVO excavator relief valve, compatible with SK220-8 SK250-8 SK260-8 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, designed for SK220-8, SK250-8, and SK260-8 excavators, is a core plug-in pressure control component of the multi-way distribution valve assembly. It is mainly responsible for limiting the pressure of the entire hydraulic system and providing overload relief protection. It directly determines the digging torque of the equipment, the response speed of the actions, and the operational stability of the entire hydraulic system.

These models, with a capacity ranging from 20 to 26 tons, have a large market share and are widely used in various operation scenarios such as earthwork engineering, infrastructure excavation, stone loading and unloading, and site demolition. During digging, raising the boom, and compound action operations, the hydraulic circuit will continuously generate high-frequency and high-pressure impacts. The relief valve can quickly open to relieve pressure when the system pressure exceeds the set value, maintaining the original factory-calibrated pressure range for the entire machine, blocking abnormal high pressure from being transmitted to the hydraulic main pump, distribution valve stem, and large and small boom oil cylinders, providing reliable overload protection for the entire hydraulic system, and ensuring stable power output for the equipment during long-term continuous operation.
