Product Specification

GVO 60186557 52111229-9802 Auxiliary Relief Valve Control Valve Pressure Relief Valve Safety Valve SY365H 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 SY365H relief valve is a core pressure protection component for the multi-channel hydraulic system of the SANY SY365H excavator. It is precisely manufactured and measured according to the original manufacturer's drawings. Thread specifications, oil hole positions, valve core stroke, and rated opening pressure are all identical to the original parts, supporting direct installation and replacement without requiring modification of the distribution valve orifice, significantly reducing the difficulty of on-site maintenance and debugging.

The product body is forged from high-quality alloy steel. The valve core mating surfaces undergo carburizing and quenching hardening treatment, and a high-precision honing process optimizes the surface finish, precisely controlling the clearance between the valve core and valve sleeve. This effectively suppresses internal leakage and stably maintains the hydraulic system's set pressure under long-term high-pressure, high-flow operating conditions.

The valve is equipped with a high-performance, high-pressure resistant fluororubber sealing kit, which withstands long-term immersion in high-temperature hydraulic oil corrosion, preventing oil seepage from the valve body surface and oil leakage due to seal aging. At the same time, the product optimizes the internal oil passage flow structure, enhances its anti-pollution ability, reduces the probability of valve core jamming and valve failure caused by impurities in hydraulic oil, reduces sudden equipment downtime for maintenance, ensures the continuous progress of engineering projects, and avoids economic losses caused by work stoppages.
