GVO 14610077 Hydraulic Check Valve Pressure Safety Valve Relief Valve EC210B EC210D EC240B EC240C Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with EC210B EC210D EC240B EC240C 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 type of threaded cartridge relief valve is a core hydraulic safety component specifically designed for the multi-way main control valve of EC210B, EC210D, EC240B, and EC240C medium-sized excavators. It is installed inside the distribution valve's valve hole and is mainly responsible for limiting the hydraulic system pressure, overloading relief and pressure stabilization in the circuit. The 21-24 ton excavators are the main models with the highest market share in the engineering sector, widely used in various heavy-load scenarios such as earthwork excavation, infrastructure construction, mining stripping, river dredging, and crushing operations.

The valve body is manufactured from high-strength alloy steel. The valve core and valve sleeve have undergone multiple precise honing and mating grinding processes. The sealing surface of the valve port has high processing accuracy, which can withstand the continuous flushing of high-pressure hydraulic oil with large flow rates for a long time, effectively resisting the wear caused by impurities in the hydraulic oil, and significantly reducing common faults such as valve core sticking and valve port erosion and internal leakage.

The entire set of valve components is equipped with a composite sealing assembly, which has excellent characteristics of high pressure resistance, aging resistance, and resistance to temperature fluctuations. Whether it is the high-temperature working conditions caused by long-term heavy-load operations or the cold machine startup in low-temperature environments, the sealing assembly can maintain stable sealing performance, minimizing problems such as system leakage and reduced pressure holding capacity caused by aging and damage to the seals.

The product is of a standard threaded cartridge structure. The thread specification, outer diameter of the valve body, oil hole position, and assembly depth are all fully in line with the standard dimensions. During maintenance and replacement, there is no need to make any processing changes to the distribution valve body. Simply insert it into the valve hole to complete the assembly. The disassembly and assembly operations are simple and efficient, significantly reducing the downtime for excavators on the construction site and fully meeting the actual operational needs of repair shops for emergency repairs and on-site rapid maintenance.
