Product Specification

GVO YN30V00120F1 YN30V00120F2 Root Pressure Relief Valve Control Valve Bypass Valve SK200-8 SK210-8 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with SK200-8 SK210-8 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

These 20-ton models have a huge market share and are widely used in various scenarios such as earth excavation, infrastructure construction, mine stripping, and site loading. During the equipment's excavation operations and the operation of compound actions, the hydraulic system frequently experiences high-pressure impacts.

This relief valve can specifically address a large number of common hydraulic faults in SK200-8, SK210-8, and SK235 models, including insufficient digging power of the entire machine, failure to operate under load, slow movement of the entire machine, failure of the system pressure to reach the specified value, continuous abnormal noise from the relief valve, poor coordination of compound actions, and pressure relief of the cylinder during lifting. In actual maintenance work, many maintenance personnel, when encountering insufficient digging power, will first assume that the main pump is worn out and damaged, but a considerable number of fault causes come from the relief valve. Valve core wear and scratches, spring fatigue, and failure of valve port sealing will all cause the system to prematurely release pressure and reduce the overall machine power.
