GVO 60114704 Return Valve Oil Supplement Valve Hydraulic Check Valve SY365H SY335H SY375H SY485 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SY365H SY335H SY375H SY485 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 plug-in type overflow valve is the core hydraulic safety component for the multi-way distribution valves of SY335H, SY365H, SY375H, and SY485 large-sized excavators. It is assembled inside the main control valve's valve hole and mainly performs key functions such as limiting the hydraulic system pressure, overloading overflow pressure relief, and regulating the pressure in the circuit. Large-tonnage excavators are widely used in high-intensity operation scenarios such as large-scale mine mining, earthwork stripping, heavy-load infrastructure construction, and stone crushing. The equipment is constantly in a high-load continuous operation state, and frequent high-pressure impacts during digging, lifting, and rotating actions can easily cause instantaneous pressure peaks in the hydraulic circuit.

The valve body is made of high-quality alloy steel materials. The valve core and valve sleeve mating pair undergo precise honing and grinding processes, ensuring precise mating clearance and high surface finish of the valve port sealing surface. It can withstand long-term erosion by high-flow high-pressure oil and effectively resist wear and scratches caused by internal impurities in the hydraulic oil, significantly reducing the probability of valve core sticking and valve port leakage. The internal pressure regulating spring is made of high-toughness alloy spring steel and is strengthened through heat treatment, with excellent fatigue resistance. It is unlikely to experience elastic fatigue attenuation or deformation fracture under repeated high-frequency pressure impacts, ensuring long-term stable pressure regulating accuracy. The entire valve assembly is equipped with a high-quality high-pressure composite sealing kit, which is resistant to high temperatures and oil corrosion, and can adapt to the harsh working conditions of mining sites with continuous operations, effectively suppressing internal leakage and external leakage, and avoiding pressure drop and sluggish actions caused by aging and failure of the seals.
