GVO 9065995 Travel Relief Valve Pressure Relief Valve Safety Valve EX100 EX120 Deere 490 490D 493D Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with EX100 EX120 Deere 490 490D 493D 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 is compatible with EX100, EX120, as well as Deere 490, 490D, and 493D excavators. It is the core main safety valve in the multi-way distribution valve assembly and is commonly referred to as the main gun by industry maintenance personnel. It is responsible for controlling the maximum working pressure of the entire hydraulic system of the machine, directly determining the excavation force of the equipment, the smoothness of the actions, and the overall safety of the hydraulic circuit.

The valve body is made of high-strength alloy steel raw materials and is formed by a single-piece processing on a high-precision CNC lathe. The core mating parts of the valve core and valve seat undergo quenching heat treatment and ultra-precision mirror surface grinding processes, significantly enhancing the surface hardness of the parts, strengthening the anti-wear and anti-fracture capabilities, and effectively resisting abrasive wear caused by impurities in the hydraulic oil. The valve components are equipped with high-performance sealing kits that are resistant to high pressure and high/low temperature aging, which can adapt to the repeated changes in oil temperature caused by the continuous operation of medium-sized excavators. Under continuous pressure shock conditions, it can effectively prevent problems such as external leakage of oil, internal pressure relief, and pressure fluctuation.
