VOE14617014 Hydraulic Check Valve Pressure Safety Valve Relief Valve EC200D EC210D EC220D EC250D EC290B EC300D Excavator Parts

Product Description

The GVO excavator relief valve, compatible with EC200D EC210D EC220D EC250D 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 plug-in type overflow valve is the core hydraulic safety component for the distribution valves of EC200D, EC210D, EC220D, and EC250D excavators. It is installed inside the main control multi-way valve's valve hole and is mainly responsible for limiting the hydraulic system pressure, overloading overflow relief, and circuit stabilization. The D series medium-sized excavators have a huge market share in the domestic engineering market and are widely used in various heavy-load scenarios such as earthwork excavation, infrastructure construction, mining stripping, river dredging, and crushing operations. During equipment operation, they often encounter sudden load changes, hard contact impacts of the bucket, and continuous pulse pressure from the crushing hammer. The hydraulic circuit may experience instantaneous high-pressure impacts at any time.

The valve body is made of high-strength alloy steel and is processed and formed. The valve core and valve sleeve undergo multiple precise honing and matching grinding processes. The sealing mating surface has high precision and can withstand the continuous flushing of high-flow hydraulic oil. It can effectively resist wear and scratches caused by impurities in the hydraulic oil and significantly reduce the failure probability of valve core sticking and internal leakage.

The entire valve assembly is equipped with a composite sealing component that is resistant to high pressure and oil temperature aging. In the environment of continuous operation in summer under high temperatures and long-term crushing conditions with rising oil temperatures, the sealing components can still maintain good sealing performance, reducing system pressure leakage and insufficient pressure maintenance caused by aging and failure of the seals.

The product is of standard threaded plug-in structure. The thread specification, valve body outer diameter, oil hole position, and assembly depth are all strictly in accordance with the original factory dimensions. During maintenance and replacement, there is no need to modify the distribution valve body or the external pipeline. It can be directly installed in the valve hole to complete the assembly. The disassembly and assembly process is simple, significantly reducing the downtime for excavators to be shut down for maintenance on the construction site. It is suitable for emergency repairs by maintenance factories and rapid maintenance of equipment to meet the actual operational needs.
