GVO XKAY-00313 Pressure Relief Valve Rotating Motor Relief Valve R110-7 R140LC-7 R160LC-7 R180LC-7 R210LC-7 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with R110-7 R140LC-7 R160LC-7 R180LC-7 R210LC-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 main relief valve is suitable for the main control distribution valves of R110-7, R140LC-7, R160LC-7, R180LC-7, and R210LC-7 series excavators. It is the core pressure control component of the entire hydraulic system and is commonly known as the main gun in the industry. It mainly undertakes the functions of pressure limitation and overload relief protection in the hydraulic main circuit. The relief valve directly determines the maximum working pressure of the entire machine, affects the excavation force, rotation torque, and power output of the slewing, and is also related to the coordination of compound actions and the operation feel.

The valve body is forged from high-quality alloy steel and undergoes multiple heat treatment processes. The valve body has both hardness and toughness, and can continuously withstand the high-frequency pulse high-pressure impact during the operation of medium-sized excavators. It is unlikely to experience valve body deformation or thread damage during long-term operation. The valve core is processed by high-precision mirror grinding technology, with strict control of the clearance, and is equipped with strengthened anti-fatigue pressure regulating springs and high-pressure resistant and aging-resistant sealing components. In complex working conditions with large temperature fluctuations at the construction site and the presence of trace impurities in the oil, the valve core responds sensitively to opening and closing, the relief and reset actions are crisp, effectively suppressing high-pressure leakage, and the equipment can maintain stable pressure regulation performance even after the oil temperature rises for a long time, suitable for various load scenarios such as earthwork excavation, impact hammer operations, etc.
