GVO 096-5931 YN22V00002F1 Pressure Relief Valve Rotating Motor Relief Valve E200B EL200B SH200 HD700 HD820 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with E200B EL200B SH200 HD700 HD820 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 compatible with E200B, EL200B, SH200, HD700, and HD820, several classic medium-sized excavator main control distribution valves. It is a crucial main pressure control valve in the entire hydraulic system of the machine, also known as the main gun in the industry. The relief valve controls the maximum working pressure of the entire hydraulic main circuit, directly determining the digging force, rotation torque, and walking power output of the entire machine, and playing a key role in the coordination of compound actions. These models are old models with a large market share. After long-term operation of the equipment, the relief valve is prone to performance degradation. Once the valve components wear out and internal leakage occurs, it will cause faults such as insufficient digging force, heavy-load pressure build-up, dropped pressure during hot operation, and jittery movements. It is a core precision hydraulic component that needs to be carefully inspected and replaced during the major overhaul of the distribution valve.

The valve body is made by forging the high-strength alloy steel as a whole, and undergoes strict quenching and tempering heat treatment processes. The overall structural strength of the valve body is enhanced, which can withstand the high-frequency and high-pressure impact and alternating loads brought by heavy-load operations of the excavator. It is unlikely to deform. The valve core is processed by high-precision mirror grinding technology, precisely controlling the clearance between the valve core and the valve hole. It is internally equipped with high-toughness anti-fatigue pressure regulating springs and high-pressure sealing components. In high-strength working conditions such as earth excavation and stone crushing, the valve core responds quickly to opening and closing actions, and releases pressure and resets quickly, effectively reducing internal leakage problems caused by valve core sticking, spring fatigue, and seal component damage. It can maintain stable pressure regulation performance even after the hydraulic oil temperature rises, and is suitable for the complex and harsh working environment of old equipment sites.
