GVO 421-43-27460 419-43-27510 204-2805 Hydraulic Valve Pressure Relief Valve Safety Valve HD250 E330C WA470-3 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with HD250 E330C WA470-3 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 HD250 excavators, E330C excavators, and WA470-3 loaders. It is a core pressure protection hydraulic component of the distribution valve and plays a role of limiting pressure and overloading relief and discharging in different models of hydraulic systems. During the excavation, loading and heavy-load operation of the equipment, instantaneous high-pressure impacts will occur. The relief valve can quickly release the excessive pressure of the system, protect the valuable hydraulic components such as the main hydraulic pump, multi-way distribution valve, and motor from being damaged due to overpressure, stabilize the working pressure of the entire machine circuit, and is a key and easily damaged accessory for engineering machinery maintenance and replacement.

The valve body is processed and formed from high-strength alloy steel substrate. The valve core undergoes high-precision grinding and quenching heat treatment processes, with high overall hardness and excellent shock resistance and fatigue resistance. For the high-flow and high-pressure working conditions of excavators and loaders, the valve core and valve sleeve are strictly controlled for the clearance of their cooperation, and high-quality high-pressure O-ring seals are matched to effectively reduce internal leakage and avoid pressure leakage and oil leakage faults. It can adapt to multi-dust and high-intensity working environments such as mines, earthwork, and stone quarries, withstand the high-temperature corrosion of hydraulic oil, and ensure the stable operation of the valve components under continuous alternating pressure conditions, effectively extending the service life of the accessories.
