GVO 360-4599 3604599 Travel Motor Relief Valve Hydraulic Safety Valve E320D E322D E323D E324D E325D E330D Excavator Parts

Product Description

The GVO excavator relief valve, compatible with E320D E322D E323D E324D E325D E330D 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 overflow valve is suitable for E320D, E322D, E323D, E324D, E325D, and E330D series excavators. It is a core pressure protection hydraulic component on the distribution valve, mainly responsible for limiting the hydraulic system pressure, providing overload overflow protection, stabilizing the working pressure of the main circuit, buffering the hydraulic shock caused by operations, protecting high-priced core components such as the main hydraulic pump, slewing motor, and multi-way distribution valve, avoiding damage to hydraulic components due to overpressure, and is a key vulnerable component for maintenance and replacement in D series models. 

The valve body is made of high-quality alloy steel and is processed as a whole. The valve core undergoes precise grinding and heat treatment processes. The overall strength is high, and the anti-shock and wear-resistant performance is excellent. Considering the working conditions of D series models with large flow and frequent pressure fluctuations, the valve core and valve sleeve are strictly controlled for the clearance, and a high-quality high-pressure O-ring is matched to effectively reduce internal leakage, withstand the erosion of high-temperature hydraulic oil, and not easily experience pressure surges or oil leakage during long-term continuous operation, making it suitable for various complex construction sites such as earthwork and mining.
