Product Description

The GVO excavator relief valve, compatible with PC240-8K PC270-8 PC290-8K 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 overflow valve assembly is compatible with PC240-8K, PC270-8, and PC290-8K excavators. It is a main pressure control valve in the distribution valve system and is a key precision component for regulating pressure and providing overload protection in the entire hydraulic system of the machine. It directly controls the maximum working pressure of the entire hydraulic system. As a medium-tonnage model with a high market share, it is widely used in various construction scenarios such as earthwork engineering, infrastructure excavation, stone work, and site backfilling.

The valve block body is machined from high-strength alloy steel and undergoes multiple machining processes such as precision milling, drilling, and honing. The internal flow path has a high degree of smoothness, ensuring smooth oil flow and reducing pressure loss. The internal valve core components are made of high-quality alloy steel and undergo quenching and tempering treatment to enhance overall hardness, impact resistance, and fatigue resistance, enabling it to withstand the high-frequency and high-pressure oil impact of medium-tonnage excavators. The valve core mating surface undergoes high-precision grinding treatment, ensuring smooth and flexible movement, effectively reducing the probability of valve sticking, valve core sluggishness, and jamming. The sealing position of the valve port is processed with strict accuracy, resistant to oil erosion, and has a stable sealing performance. The entire set of sealing components is made of high-quality sealing materials that are resistant to high pressure, resistant to hydraulic oil corrosion, and resistant to high and low temperature aging, minimizing internal leakage and external oil seepage problems, and perfectly adapting to complex and harsh working conditions in construction sites with high dust, large oil temperature fluctuations, and oil containing impurity particles.
