Product Specification

GVO 708-25-04311 723-40-93600 723-40-93601 Main Relief Valve Pressure Relief Valve Safety Valve PC200-8 300-7 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

This GVO high-precision cartridge-type hydraulic relief valve is a universally applicable design for Komatsu's classic main models, suitable for various tonnages. It precisely adapts to the PC200-8 20-ton electronically controlled medium-duty excavator and the PC300-7 30-ton heavy-duty mining excavator. As a multi-way distribution valve cartridge-type main relief valve, it is commonly referred to in the industry as a hydraulic main valve, overload safety valve, or system pressure regulating valve. It serves as the core pressure reference and overload safety protection component for the hydraulic systems of these two excavators with different tonnages and operating positions.

The product offers flexible and diverse sales models. It supports individual retail sales to machine owners for self-repair of equipment malfunctions, as well as bulk wholesale supply to domestic construction machinery parts dealers and chain repair shops. It is also highly compatible with export orders for construction machinery parts to Southeast Asia, Africa, the Middle East, and South America.

The product is individually packaged in a thickened cardboard box with shock-absorbing foam inserts, effectively resisting impacts, thread damage, and valve body surface scratches during long-distance land and ocean transport, ensuring high reliability in cross-border logistics.

Compared to the high procurement cost of Komatsu's original imported relief valves, this product, with its original factory-grade machining precision, pressure resistance, and service life, significantly reduces customers' maintenance and procurement budgets. After equipment repair, the power output and pressure stability are almost indistinguishable from new machine levels. At the same time, it takes into account durability, economical use, and comprehensive after-sales support. It is the preferred cartridge valve for major overhauls of the hydraulic systems of Komatsu 20-ton PC200-8 and 30-ton PC300-7 excavators, as well as for stocking readily available wear parts.
