Product Specification

GVO 419-43-27510 Hydraulic Valve Pressure Relief Valve Safety Valve WA320-3 WA300-3A WA350-3A WA400-3A WA450-3 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with WA320-3 WA300-3A WA350-3A WA400-3A WA450-3 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 wheel loaders of the WA320-3, WA300-3A, WA350-3A, WA400-3A, and WA450-3 series. It is a crucial pressure protection valve component on the hydraulic distribution valve. During the operations of loading, lifting, and discharging materials, the loader will experience frequent impact loads. The relief valve is responsible for limiting the system pressure and performing overload relief and discharging functions. It promptly releases the excessive high pressure in the hydraulic circuit, effectively protecting the main hydraulic pump, multi-way distribution valve, steering hydraulic components, and other core components, preventing damage caused by overpressure, and stabilizing the hydraulic working pressure of the entire machine. It is a frequently used hydraulic accessory for the maintenance and repair of this series of loaders.

The valve body is machined from high-strength alloy steel, and the valve core undergoes precise grinding and heat treatment processes to enhance the overall hardness and impact and wear resistance. To meet the characteristics of the large-flow hydraulic system of the -3 series loaders, the valve core and valve sleeve are precisely controlled for the clearance between them, and high-quality high-pressure sealing components are matched to effectively reduce internal leakage of the valve body and prevent leakage and oil seepage faults. The product can long-term adapt to heavy-duty working conditions such as sand and gravel yards and construction sites, withstand temperature fluctuations and alternating pressure impacts, extend the service life of the valve components, and reduce equipment downtime and maintenance time.
