Product Specification

GVO HVME400-070000 Auxiliary Relief Valve Control Valve Pressure Relief Valve Safety Valve SY485 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

The GVO SY485 relief valve is a core pressure protection component adapted to the hydraulic system of the SANY SY485 large excavator. It is structurally replicated and precision-machined strictly according to the original factory drawings. The thread specifications, oil hole positions, valve core stroke, and opening pressure parameters are highly matched to the original parts, allowing for direct, non-destructive replacement by inserting it into the multi-way valve orifice without on-site valve body modification.

The product body is forged from high-strength alloy steel. The valve core mating surfaces undergo quenching hardening and high-precision honing processes to precisely control the mating clearance. This effectively reduces internal leakage under high-flow, high-pressure continuous operation, stably maintaining the hydraulic system's set working pressure. It specifically addresses common faults in SANY SY485 equipment, such as pressure drop under heavy load, weak digging power, overflow noise, and jamming during complex movements. It stably regulates oil pressure in high-intensity operation scenarios such as earthmoving and mining, ensuring continuous power output for the entire machine.

The valve is equipped with high-pressure resistant, anti-aging fluororubber sealing components, which can resist continuous corrosion from high-temperature hydraulic oil and prevent oil leakage due to external valve body leakage or seal failure. The product optimizes the internal flow channel structure, enhances anti-contamination capabilities, reduces the probability of valve core jamming and valve failure caused by impurities in hydraulic oil, reduces the frequency of unexpected equipment downtime for maintenance, and ensures continuous construction of engineering projects.
