Product Specification

GVO 4373201 Rotating Motor Relief Valve Pressure Relief Valve EX100-3 EX120-3 EX120-5 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with EX100-3 EX120-3 EX120-5 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 type of relief valve is suitable for EX100-3, EX120-3, and EX120-5 excavators. It is a key pressure protection component within the distribution valve assembly. Its main function is to limit the pressure in the hydraulic circuit and provide overload relief. It can absorb the hydraulic shock generated during operation, stabilize the system working pressure, and protect the main hydraulic pump, multi-way distribution valve, and rotation motor, which are the core hydraulic components. It prevents damage to the components caused by system overpressure. It is a frequently replaced and easily damaged accessory for older medium-sized excavators during maintenance.

The valve body is manufactured from high-strength alloy steel, and the valve core undergoes precise grinding and heat treatment processes. The surface is wear-resistant and shock-resistant. According to the hydraulic system characteristics of EX-3 and EX-5 models, the clearance between the valve sleeve and the valve core is strictly controlled. It is combined with oil-resistant and aging-resistant high-pressure sealing O-rings to effectively reduce internal leakage of the valve body, minimize cross-pressure and oil leakage faults. It can long-term adapt to various working conditions such as earthwork operations and miscellaneous tasks on construction sites. It can withstand temperature changes and maintain stable working performance under continuous alternating pressure environments.
