VOE14513144 VOE14513185 Auxiliary Relief Valve Safety Valve EC460B EC460C EC460CHR EC700B EC700C Excavator Parts

Product Description

The GVO excavator relief valve, compatible with Hitachi 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

GVO relief valves, compatible with EC460B/EC460C/EC460CHR, adhere to high-standard manufacturing specifications for hydraulic components in engineering machinery. A comprehensive quality control system is in place, encompassing raw material warehousing, rough and fine machining, heat treatment, precision grinding, dust-free assembly, and finished product inspection.

The valve body is made of high-quality alloy steel, undergoing deep heat treatment for strengthening, precision CNC cutting, and high-precision internal honing. The internal valve core undergoes meticulous mating and grinding, strictly controlling the movement clearance to minimize internal leakage during operation.

When the operating oil pressure exceeds the system's rated range, the relief valve opens quickly and sensitively, smoothly releasing pressure, effectively buffering instantaneous high-pressure impacts. It provides comprehensive protection for expensive and precision components such as the hydraulic main pump, multi-way distribution valve, and high-pressure hydraulic pipelines, preventing major hydraulic failures such as valve bore damage and pipe rupture. The product's installation outer diameter, thread specifications, and port layout fully conform to original equipment manufacturer (OEM) standards.

It supports direct plug-in non-destructive replacement without additional processing or debugging. The pressure adjustment parameters are highly matched with the original hydraulic settings of series of machines. The pressure is not easy to drift during long-term continuous heavy-load operation, making it very suitable for high-intensity construction scenarios such as mining, large-scale earthwork, and infrastructure projects.
