GVO 9102256 9114686 9115733 9134147 Pressure Relief Valve Hydraulic Safety Valve Control Valve EX200-3 EX200-2 EX200-5 Excavator

Product Description

The GVO excavator relief valve, compatible with EX200-3 EX200-2 EX200-5 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 the EX200-2, EX200-3, and EX200-5 excavators, is a core pressure control plug-in valve component within the main control distribution valve. It is responsible for limiting the maximum working pressure of the entire hydraulic system of the machine and establishing a crucial overload protection line for the entire hydraulic circuit.

The valve body of this overflow valve is made by forging with high-strength alloy steel as a whole, and undergoes quenching and tempering treatment. The overall structural strength of the valve body is high, and it has excellent resistance to impact and erosion. It can withstand the repeated impact and erosion of high-pressure hydraulic oil under the working conditions of construction machinery for a long time. The valve core and valve seat are processed by high-precision matching grinding technology, forming a precise micro-level clearance, which ensures that the valve component responds sensitively and rapidly during overload relief, and maintains a tight closed state during normal operation of the equipment, minimizing internal leakage of the valve component and avoiding unnecessary premature overflow that causes system power loss.

The working surface of the valve core is strengthened for wear resistance, which can withstand the erosion and scratching caused by impurities mixed in the hydraulic oil, reduce the probability of valve jamming due to impurities, and effectively extend the actual service life of the component. The entire sealing assembly uses high-quality sealing gaskets resistant to high pressure and corrosion by hydraulic oil. It is suitable for the wide temperature working range of construction machinery, does not soften or age easily in high-temperature environments, and does not harden or crack in low-temperature conditions. This ensures reliable prevention of valve body oil leakage and internal oil leakage, fully adapting to the harsh working sites with much dust and inconsistent oil quality.
