GVO LC22V00006F1 YN22V00013F1 Travel Motor Pressure Relief Valve GM60 Safety Valve SK200-6 SK200-8 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SK200-6 SK200-8 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 group of models covers mainstream machines of 20-ton class, and is widely used in complex construction sites such as earthwork infrastructure, mining operations, heavy-load loading, and earth and rock excavation. During excavation operations and compound action operations, the hydraulic circuits will frequently endure instantaneous high-pressure impacts. The relief valve will quickly open to relieve pressure when the system pressure exceeds the set threshold, stabilizing the overall machine pressure within the original factory standard range, avoiding abnormal high-pressure impacts that could damage high-value components such as the main hydraulic pump, distribution valve group, and large and small arm oil cylinders. This builds a reliable safety barrier for the entire hydraulic system, ensuring stable power output for the equipment during long-term heavy-load operations.

This relief valve can specifically address various hydraulic pressure failures commonly encountered by SK200-6, SK200-8, SK330-8, SK350-8, and SK350-9 models, including insufficient heavy-load excavation, machine and pressure build-up during heavy-load operations, slow overall action speed, system pressure not reaching the specified value, continuous abnormal noise and vibration at the relief position, uncoordinated compound actions of the large and small arm buckets, and oil cylinder sagging and pressure relief. In actual maintenance scenarios, many maintenance personnel often first assume that the hydraulic main pump is worn out when encountering insufficient excavation power, but the majority of the fault causes stem from the relief valve: valve core damage and wear, spring fatigue and softening, and valve port sealing failure, which can cause the system to prematurely overflow and relieve pressure, resulting in a significant decrease in the overall machine's power.
