Product Specification

GVO 4194327510 419-43-27510 Hydraulic Valve Pressure Relief Valve Safety Valve WA380 WA420 WA320 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with WA380 WA420 WA320 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 small-sized WA320, WA380, and WA420 wheel loaders. It is a core pressure-protective hydraulic component of the distribution valve assembly, mainly responsible for limiting pressure and overloading relief in the hydraulic system. During the loading, lifting, and unloading operations of the loader, frequent impact pressures will be generated. The relief valve can promptly release the excessive high pressure in the circuit, protecting the main hydraulic pump, multi-way distribution valve, steering components, and other valuable parts from being damaged due to overpressure, stabilizing the hydraulic working range of the entire machine. It is a key component commonly used for maintenance and major repairs of the series of loaders.

The valve body is forged from high-strength alloy steel, and the valve core undergoes precise grinding and heat treatment processes, with high hardness, good shock resistance, and wear resistance. For the working conditions of wheel loaders with large flow and frequent alternating pressures, the clearance between the valve core and the valve sleeve is strictly controlled, and high-quality high-pressure sealing components are matched to effectively control internal leakage and prevent oil leakage and pressure leakage faults. It can adapt to dusty and harsh working conditions such as material yards and construction sites, withstand the high-temperature aging of hydraulic oil, maintain stable performance under long-term heavy-load operation conditions, and effectively extend the service life of the valve components.
