GVO 421-43-27460 4214327460 Hydraulic Valve Pressure Relief Valve Safety Valve WA350-3 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with WA350-3 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 type of relief valve is suitable for the WA350-3 wheeled loader and belongs to an important pressure protection component of the entire hydraulic system. It is installed inside the distribution valve and mainly performs the core functions of limiting system pressure and releasing overload pressure. The operating conditions of the loader are complex and variable. During the processes of loading, lifting, and discharging, frequent hydraulic shocks will occur. The relief valve promptly releases the excessive pressure in the circuit, protecting the hydraulic pump, multi-way valve, and steering hydraulic components from being damaged by high-pressure shocks, ensuring that the entire hydraulic system is within a safe working range. It is a key hydraulic component for the maintenance and repair of the WA350-3 loader.

The valve body is forged from high-strength alloy steel, and the valve core undergoes precise grinding and heat treatment to enhance surface hardness and fatigue resistance. In response to the working conditions of the wheeled loader, which have large flow rates and frequent pressure fluctuations, the clearance between the valve core and the valve sleeve is strictly controlled. Combined with high-quality high-pressure sealing rings, it effectively controls internal leakage and prevents oil leakage and pressure leakage faults. It can withstand the high-frequency pressure shocks brought by heavy loading during the operation, is resistant to oil temperature aging, and is suitable for harsh operating environments such as sand and gravel yards and construction sites. This ensures the long-term service life of the valve components.
