GVO XKAY-00676 XKAY00676 Pressure Relief Valve Rotating Motor Relief Valve Safety Valve R55-7 R55W-3 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with R55-7 R55W-3 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 compatible with the distribution valve of the R55-7 crawler excavator and the R55W-3 wheeled excavator. It is a pressure protection component for the hydraulic system branch, commonly known as the auxiliary gun in the industry. It mainly controls the limited pressure of the main boom, small boom, and bucket working circuits, and plays an important role in protecting the system from overload and pressure relief. As a key precision component inside the main control valve of the 5-ton small excavator, the overflow valve directly determines the output force of a single action and protects the oil cylinder, oil pipe, and valve body from instantaneous high-pressure impacts. Once the valve component's performance deteriorates, it will directly cause problems such as insufficient action force, arm drop, and inability to adjust the pressure properly. This is a key component for maintenance and replacement when repairing this small excavator, and its stability directly affects the overall performance of the machine in various construction scenarios, including earthwork operations and crushing operations.

The valve body is forged from high-strength alloy steel as a single piece, and undergoes quenching and tempering heat treatment to enhance its strength and impact resistance. It has high overall hardness and excellent resistance to impact. It can effectively cope with the pulse pressure impacts caused by frequent steering and reversing of wheel excavators and small excavators, as well as crushing operations. The valve core is precisely ground to control the clearance between the valve core and the valve sleeve, and is equipped with strengthened anti-fatigue springs inside. It is also combined with a sealing component that is resistant to high pressure and corrosion by hydraulic oil. This effectively prevents internal leakage under high-pressure conditions. In complex construction scenarios on the job site, the valve core responds sensitively to opening and closing, and the pressure relief and reset actions are crisp. This can effectively avoid various problems such as valve core jamming, weak springs, and aging seals, improving common faults such as the sinking of the main boom, insufficient retraction and extension of the bucket, and action stalling. It is suitable for various construction scenarios including landscaping, earthwork excavation, and crushing operations.
