Product Description

The GVO excavator relief valve, compatible with EC200D EC210D EC220D 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 relief valve is a core hydraulic safety component specifically designed for the main control valves of the EC200D, EC210D, and EC220D series excavators. It is installed inside the distribution valve and is responsible for the important functions of limiting the pressure of the entire hydraulic system, overloading relief and pressure stabilization of the circuits. The D series medium-sized excavators, with their stable and reliable overall performance, are widely used in various heavy-duty working conditions such as earthwork excavation, infrastructure construction, mining operations, and river channel improvement. During operation, sudden load changes, bucket impacts, and high-frequency operation of the breaker occur frequently.

The valve body is manufactured from high-hardness alloy steel. The valve core and valve sleeve are precisely honed and matched, and are paired with high-precision ground sealing surfaces. It can withstand long-term repeated flushing by high-flow high-pressure hydraulic oil, effectively resisting wear caused by internal impurities in the hydraulic oil, and reducing the probability of valve core sticking and seal leakage. The entire set of valve components is equipped with high-pressure-resistant and aging-resistant high-quality sealing components, which can adapt to the temperature changes of the oil under the long-term high-load operation of the equipment. In a continuous high-temperature working environment, it still maintains excellent sealing performance, significantly reducing problems such as system leakage and pressure loss caused by aging of the sealing components. The product has a standard plug-in thread structure. The thread pitch, valve body outer diameter, oil hole position, and assembly depth are all strictly in accordance with the original vehicle specifications. During maintenance and replacement, there is no need to modify the distribution valve at all. Simply insert it into the valve body hole to complete the assembly. The disassembly and assembly operations are simple and quick, greatly reducing the downtime for equipment maintenance on the construction site. It is highly suitable for on-site emergency repairs by maintenance factories and rapid equipment maintenance operations.
