410127-00676 Main Pressure Relief Valve Control Valve Hydraulic Safety Valve DX800 DX1000HD HX1000AL DX1000LC-7 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with DX800 DX1000HD HX1000AL DX1000LC-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, designed for use with DX800 and DX1000HD super-large mining excavators, is the core pressure protection component within the main control distribution valve. It is specifically tailored for thousand-ton mining heavy-duty equipment, regulating the extreme working pressure of the entire hydraulic system. It is mainly used for large-scale mining stripping and heavy-duty earth and rock excavation. The equipment has a huge operating load, and during operations such as digging, lifting, rotating, and crushing, the hydraulic circuit will frequently experience intense instantaneous high-pressure impacts.

The valve body itself is forged from high-grade alloy steel and undergoes multiple quenching and tempering treatments. The overall strength of the valve body is high, and it has strong resistance to high-pressure impacts. It can withstand the frequent and high-pressure hydraulic oil flushing under mining conditions for a long time. The valve core and valve seat are manufactured using high-precision matching grinding technology, achieving a precise micrometer-level clearance. This ensures rapid overflow opening response while also enabling tight closure under normal working conditions, minimizing internal leakage and preventing premature overflow and pressure relief, thus reducing power loss. The working surface of the valve core is strengthened for wear resistance, which can withstand the erosion and scratching caused by metal impurities particles mixed in the hydraulic oil, significantly extending the service life of the components.
