Product Description

The GVO excavator relief valve, compatible with PC200-6  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 main overflow valve on the distribution valve assembly of the PC200-6 excavator. It is also a crucial pressure control and protection component of the entire hydraulic system of the machine. It is commonly known as the main gun in the industry. Its main function is to control the maximum working pressure of the entire hydraulic system of the PC200-6 machine, providing overload safety protection for the entire hydraulic system.

The valve body is manufactured from high-strength alloy steel and undergoes a quenching and tempering heat treatment process to enhance the hardness, structural strength, and fatigue and impact resistance of the valve body. The valve core is machined using high-precision grinding, and the sealing position of the valve orifice is processed through precise matching and grinding. The valve core moves smoothly and flexibly, effectively avoiding problems such as valve jamming and valve core jamming during operation. The sealing surface of the valve orifice can withstand long-term, high-frequency, and high-pressure oil flushing, with excellent wear resistance and erosion resistance. The entire valve assembly is equipped with a complete set of high-quality sealing components. The sealing ring is made of materials that are resistant to high pressure, hydraulic oil corrosion, and aging, which can effectively prevent oil leakage inside the valve and external leakage. It is perfectly suitable for harsh working conditions in old equipment operation sites with high dust, large oil temperature fluctuations, and excessive oil impurities.
