Product Description

The GVO excavator relief valve, compatible with PC40 PC45 PC50 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 PC40, PC45, and PC50 small excavators, is a crucial plug-in pressure control valve in the distribution valve assembly. It plays a crucial role in limiting the maximum working pressure of the entire hydraulic system, forming a complete overload protection barrier for the entire hydraulic circuit.

The valve body of this overflow valve is forged from high-strength alloy steel as a whole and undergoes a complete hardening treatment. The structural strength of the valve body is high, with excellent resistance to impact and oil erosion. It can withstand the repeated high-pressure oil impact caused by the frequent operation of small excavators. The valve core and valve seat are processed using a high-precision matching grinding method, achieving a precise gap of micrometers, which ensures a sensitive and rapid overflow pressure relief response even under overload conditions. During normal operation, it can tightly close, minimizing internal leakage of the valve components and avoiding power loss caused by abnormal overflow.

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. This reduces the probability of valve core jamming faults and effectively extends the actual service life of the components. The entire sealing assembly uses high-quality sealing rings that are resistant to high pressure and corrosion by hydraulic oil. It is suitable for a wide range of working temperature intervals of small excavators, does not soften or age easily under high-temperature conditions, and does not crack under low-temperature environments. This completely eliminates the problems of oil leakage from the valve body and internal oil leakage from the inside, and is fully adapted to the harsh working environment with much dust and inconsistent quality of hydraulic oil on construction sites.
