Product Description

The GVO excavator relief valve, compatible with DX300LC DX340LC DX380LC DX420LC DH300-5 DH340-7 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

It is compatible with Doosan DH300, DH370-7, DX300 models, as well as Sumitomo SH300A3, SH460. The disassembly and assembly are convenient. It can directly replace the original vehicle parts without additional modification or debugging. The product is processed strictly according to the original factory size. The threads, installation holes, and oil ports are all fully matched with the original vehicle. The assembly fit is high, and it can be directly used for equipment maintenance and replacement. It is also suitable for equipment major repairs, complete machine refurbishment projects. The inventory is sufficient, and it is suitable for repair shops, parts suppliers, and engineering sites' rapid part replacement needs.

The valve body is made of high-strength alloy steel substrate. The valve core undergoes precise grinding and heat treatment processes. The overall hardness is high, and it is resistant to impact. It can withstand the high-frequency and high-pressure impact during the operation of large-scale equipment for a long time. The sealing parts are equipped with high-quality oil-resistant rubber O-rings. The processing tolerances are strictly controlled to effectively reduce internal leakage and prevent oil leakage and pressure leakage faults. It is suitable for high-intensity construction sites in mines and earthwork, with high temperature resistance and resistance to hydraulic oil corrosion, significantly extending the service life of the parts.
