GVO 31N6-18003 JADG-1004 Pressure Relief Valve Rotating Motor Relief Valve R60-5 R80-7 SK60-5-7 SK70 SK75UR SH60 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with R60-5 R80-7 SK60-5-7 SK70 SK75UR SH60 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 branch overflow valve is suitable for the distribution valves of various small-sized excavators such as R60-5, R80-7, SK60-5, SK60-7, SK70, SK75UR and SH60. It is a pressure protection valve for the hydraulic system branch and is commonly known as a secondary gun in the industry. It is mainly responsible for limiting the pressure of the main boom, small boom and bucket branches and releasing the overload pressure. It protects the corresponding hydraulic cylinders and pipelines from instantaneous high-pressure impacts, directly affecting the digging force and the stability of the retraction and extension actions. It is a highly precise hydraulic component with a high repair and replacement frequency for small excavators of 6-8 tons. In earthwork, landscaping and construction crushing operation conditions, the reliability of the overflow valve's operation directly affects whether the entire machine operates powerfully and avoids damage to the cylinder seals, oil pipes and internal components of the main control valve due to excessive local pressure. 

The valve body is forged from high-strength alloy steel and undergoes quenching and tempering heat treatment. The overall anti-shock and anti-deformation ability is strong, which can adapt to the frequent start-stop operation of small excavators and the high-frequency impact of impact hammers. The valve core is processed by high-precision grinding, with strict control of the clearance. It is combined with anti-fatigue springs and oil-resistant and aging-resistant sealing kits to effectively reduce internal leakage under high-pressure conditions. Facing the pulse pressure impact brought by crushing operations, the valve core responds sensitively to opening and closing, releases pressure quickly and resets neatly, reducing problems such as valve core sticking, spring fatigue failure, and improving the occurrence of faults such as arm dropping, action jamming, and insufficient local pressure in the equipment, which is suitable for the complex and variable construction operation conditions of small excavators.
