Product Specification

GVO RD80970810 Main Relief Valve Pressure Relief Valve Hydraulic Safety Valve KX080-3 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 offers bulk stock of 923G1 4V28-0 relief valves, compatible with the popular Kubota KX080-3 8-ton mini excavator. Ample inventory is available to support large-volume orders. Products strictly replicate original factory processing standards; each relief valve undergoes high-pressure testing on a hydraulic bench before leaving the factory to eliminate defective products due to jamming, pressure leakage, or seepage, ensuring consistent and high-quality output.

Precisely compatible with your machine, direct installation without damage. Designed specifically for the Kubota KX080-3, the valve body dimensions, thread pitch, and oil passage positions are 1:1 identical to the original parts, making disassembly and assembly simple and maintenance/replacement a breeze.

Precision valve core, stable pressure without drift. The high-precision ground valve core, combined with a balanced pressure-regulating spring, ensures continuous pressure maintenance during high-intensity operation of the hydraulic breaker, eliminating issues of fluctuating power and providing a smooth, linear operating feel.

Hardened alloy steel valve body, rugged and durable for construction sites. The tempered and thickened valve body, combined with multi-layer high-pressure resistant sealing rings, resists the erosion of mud and dust, and is not prone to oil leakage and pressure loss under high and low temperature and continuous high pressure conditions.
