GVO 723-40-72700 7234072700 Pressure Relief Valve Pressure Reducing Valve pilot Valve PC400-7 PC400LC-7 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC400-7 PC400LC-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 overflow valve assembly is suitable for PC400-7 and PC400LC-7 heavy-duty excavators. It is the main pressure control valve of the distribution valve system, also known as the main gun in the industry. It is a core precision component that directly controls the maximum working pressure of the entire machine's hydraulic system. It is a crucial component for achieving pressure regulation and overload safety protection in the hydraulic system of the entire machine, and is widely used in high-intensity operation scenarios such as mining quarrying, earth and rock stripping, large-scale infrastructure excavation, and heavy-duty earthwork. The hydraulic system operates under high flow and high pressure conditions for a long time.

The valve block body is made of high-strength alloy steel and undergoes multiple precision processing procedures such as CNC precision milling, drilling, and internal flow channel honing. The inner wall of the valve block's flow channels has high smoothness, allowing for smooth oil flow and effectively reducing fluid resistance and pressure loss, thereby improving the working efficiency of the high-flow hydraulic system. The internal valve core assembly is made of high-quality alloy steel and undergoes quenching and tempering heat treatment to significantly enhance the hardness, impact resistance, and fatigue resistance of the valve core, enabling it to withstand the frequent and intense high-pressure oil impact during heavy-duty excavator operations.

The valve core mating sealing surface is processed using high-precision grinding technology. The valve core moves flexibly and smoothly, minimizing the risk of valve sticking, valve core sluggishness, and jamming. The sealing part of the valve port is precisely machined with strict accuracy, able to withstand continuous erosion from high-flow high-pressure oil, ensuring long-lasting and reliable sealing performance. The entire set of sealing components is made of high-performance sealing materials that are resistant to high pressure, resistant to hydraulic oil corrosion, and resistant to high and low temperature aging. This ensures minimal leakage within the valve body and external oil leakage or oil seepage, fully adapting to the harsh working environment of mining sites with high dust, large temperature fluctuations, and impurities in the hydraulic oil.
