Product Description

The GVO excavator relief valve, compatible with R55 R60 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 the overflow valve for R55 and R60 excavators. It features an alloy steel forged valve body, precisely ground valve core, reinforced anti-fatigue spring, and is resistant to internal leakage and shock. It can be directly interchanged with the original position without any modification. It solves problems such as offloading, single-action weakness, and pressure attenuation during hot start. The hydraulic calibration is carried out on a test bench and the valve is factory-assembled. It is suitable for both crawler and wheeled small excavators for maintenance and replacement. 

Each finished overflow valve undergoes professional hydraulic testing on a dedicated test bench. It completes tests such as high-pressure pressure resistance test, pressure calibration verification, internal leakage detection, and multiple cycles of opening and closing durability test. Unqualified products with pressure drift or excessive leakage are strictly screened out to ensure that each valve component delivered meets stable performance standards. Replacing this overflow valve can precisely and stably control the pressure of each working device branch, prevent the system from overloading and damaging expensive components such as cylinder seals, high-pressure hoses, and main control valves, avoid secondary faults caused by abnormal pressure, and effectively reduce the subsequent major overhaul costs of the entire machine. Whether it is equipment major repair, distribution valve maintenance, or emergency replacement of faulty parts, it can restore the original operational power of the equipment.
