GVO 723-40-71800 7234071800 Pressure Relief Valve Pressure Reducing Valve Pilot Valve PC300-8 PC400-8 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC300-8 PC400-8 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 PC300-8 and PC400-8 heavy-duty excavators. It is the main pressure control valve in the hydraulic system of the distribution valve, also known as the main gun in the industry, and it plays a core role in limiting the pressure of the entire hydraulic circuit and providing overload safety protection. It is widely used in high-intensity operation scenarios such as mining quarrying, large-scale earthwork 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 is smooth and clean, effectively reducing the resistance of oil flow and minimizing pressure loss. This fully meets the requirements of large-flow hydraulic output of heavy-duty models, enhancing the working efficiency of the entire hydraulic system. The internal valve core components are made of high-quality alloy steel and undergo quenching and tempering heat treatment for strengthening, significantly improving the hardness, impact resistance, and fatigue resistance of the valve core. They can withstand frequent and intense high-pressure oil impact in mining operation environments. The valve core mating sealing surface is processed by high-precision grinding technology, ensuring the valve core's flexible and smooth reciprocating motion, significantly reducing the probability of valve sticking, valve core sluggishness, and jamming. The sealing part of the valve port is processed with strict accuracy, able to withstand continuous erosion by high-flow and high-pressure oil, and maintains a reliable sealing performance for a long time.
