Product Specification

GVO RD80970810 Auxiliary Relief Valve Pressure Relief Valve Hydraulic Safety Valve KX080-3 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with Hitachi 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

The GVO KX080-3 main relief valve is specifically designed for the hydraulic system of the Kubota KX080-3 mini excavator and is a core component for overall pressure control. The valve body is forged from high-strength alloy steel in one piece, and the internal precision valve core undergoes high-precision grinding. It is equipped with oil-resistant and wear-resistant fluororubber seals, making it suitable for long-term heavy-duty operation and alternating high and low temperature conditions.

It precisely controls the main hydraulic circuit pressure, providing rapid pressure relief and buffering in case of overload, preventing damage to the hydraulic pump and distribution valve due to overpressure bursting. It stabilizes the excavator's digging, swinging, and traveling movements, eliminating common malfunctions such as stalling, weak movement, boom drop, and abnormal noises.

The threaded cartridge structure allows for easy installation and removal. The sealing points match the original factory standard, allowing direct replacement of the original relief valve without modification. It is suitable for continuous operation in various scenarios such as earthmoving, crushing, and landscaping, providing long-term stable hydraulic output and significantly reducing equipment maintenance frequency.
