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 relief valve, compatible with EC460 and Hitachi ZX450 hydraulic systems, is manufactured in strict accordance with high-standard manufacturing specifications for hydraulic components in construction machinery. A comprehensive quality control system has been established, encompassing raw material warehousing, rough and fine machining, heat treatment and hardening, precision grinding, dust-free assembly, and finished product inspection.

Addressing the common operating environments in construction sites where hydraulic oil contains many impurities and operating temperatures fluctuate significantly, the valve core flow channel structure has been optimized to enhance overall resistance to contamination and impurities, greatly reducing high-frequency hydraulic failures such as valve core jamming and internal wall scoring.

Equipped with oil-resistant, high-temperature-resistant, and anti-aging high-performance sealing components, it maintains stable sealing performance under both high and low temperature conditions, preventing problems such as oil leakage and insufficient pressure relief during prolonged operation.
