Product Description

The GVO excavator relief valve, compatible with PC200-7-8 PC300-8 PC450-7 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 is the core pressure control component for the distribution valves of PC200-7, PC200-8, PC300-8, and PC450-7 excavators. As the main overflow valve of the hydraulic system, it directly determines the maximum working pressure of the entire hydraulic system and assumes the key function of overload protection for the system. 

The valve body is made of high-hardness alloy steel as the basic material. The entire set of valve cores undergoes quenching and tempering heat treatment, significantly enhancing the overall strength and impact resistance of the valve body. The valve cores are processed by high-precision mirror grinding, and the valve port positions are precisely ground to ensure smooth reciprocating motion of the valve core without any jamming or stalling. The valve port sealing surfaces have extremely strong resistance to oil liquid erosion and wear. 

All the sealing rings are made of high-quality sealing components that are resistant to aging, high pressure, and hydraulic oil corrosion. They can effectively avoid internal leakage and external leakage, and perfectly adapt to the harsh working environments on construction sites, such as high dust, large diurnal temperature differences, and abundant oil impurities. The product strictly complies with the original vehicle and original factory size standards. The thread specifications, sealing slots, and valve core stroke are all highly matched with the original vehicle parts, allowing for direct disassembly and replacement during maintenance without any modifications to the pipeline. This effectively reduces the on-site maintenance and disassembly time, facilitating the rapid completion of equipment emergency repairs by maintenance workshops.
