Product Specification

24201225 YT22V00003F1 Main Relief Valve Pressure Relief Valve Safety Valve SK75-8 LG907 SH120 R205-7 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 multi-model universal relief valves are readily available, compatible with Kobelco SK75-8, Lingong LG907, and Sumitomo SH120 excavator distribution valves. Installation dimensions are compatible with original equipment manufacturer (OEM) parts, ensuring strong adaptability. The valve body undergoes quenching and hardening treatment, making it corrosion-resistant and wear-resistant. Seals are made of imported materials resistant to high and low temperatures, suitable for harsh working conditions such as dusty, high-temperature, and heavy-load environments.

The valve body cavity is precision honed, and an internal high-temperature alloy pressure-resistant spring prevents fatigue deformation during long-term high-frequency opening and closing.

A multi-layer sealing structure isolates hydraulic oil impurities and high-temperature corrosion, significantly reducing the probability of oil leakage and pressure relief failures. Available in two specifications: main relief and branch overload relief, protecting the main hydraulic circuit and the boom, stick, and travel branch circuits respectively, providing double buffering against hydraulic pressure shocks.

Each finished product undergoes individual pressure testing, resulting in minimal pressure error, reducing the frequency of major overhauls of the distribution valve and main pump, and extending the service life of the entire hydraulic assembly.
