Product Description

The GVO excavator relief valve, compatible with PC300-7 PC300-8 PC350-7 PC350-8 PC400-7 PC450-7 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 is a super-large mining excavator. It is constantly used in extreme high-intensity working conditions such as mining stone extraction, large-scale earth and rock excavation, and heavy-load loading. The hydraulic system continuously withstands huge alternating pressure impacts. The stability performance of the relief valve directly determines the overall operation efficiency and equipment safety of the entire machine.

This type of relief valve has strong cross-model maintenance adaptability. Its assembly structure is consistent with the original vehicle parts. It can be quickly disassembled, installed and replaced at repair shops and on-site at mining sites, minimizing the downtime for equipment maintenance and reducing huge economic losses caused by project. The product combines excellent quality with high cost-effectiveness. It is suitable for single equipment fault repair and replacement, as well as large-scale bulk stocking by machinery parts distributors. It covers the domestic market and overseas parts circulation channels.
