Hydraulic Pump Parts Traveling Motor Relief Valve LG85 Pressure Safety Main Valve for Construction Machinery Excavators Parts

Product Description

The GVO excavator relief valve, compatible with LG85  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

LG85 excavator relief valve, main control valve pressure protection component. The valve body is precisely machined from alloy steel, the valve stem is hardened for wear resistance, and the sealing components are anti-aging and prevent internal leakage. It is used to limit the maximum pressure of the hydraulic system, achieve overload protection, and solve problems such as weak digging machine operation, unstable pressure, and loud overflow noise. 

The relief valve is often in high-frequency and high-pressure conditions, which can easily cause valve stem wear, spring fatigue, and aging of the sealing ring, subsequently leading to overall machine sluggishness, difficulty in pressure establishment, and continuous abnormal noise during overflow. This model of relief valve optimizes the processing accuracy of the valve stem, reduces wear and sticking caused by hydraulic oil impurities, and the stable internal spring ensures sensitive pressure response. The sealing components are resistant to oil and high temperatures, extending the service life of the valve components. The installation dimensions of the valve components are fully in line with the original factory standards. During maintenance, they can be directly disassembled and replaced without modifying the pipelines, quickly restoring the hydraulic power of the excavator. Compared to replacing the entire set of distribution valves, it significantly reduces maintenance costs and is the preferred accessory for hydraulic maintenance of small excavators.
