Product Specification

GVO 31N6-17740 Distributor Valve Pressure Relief Valve Hydraulic Safety Valve R305 R215 R225 R385 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

The GVO relief valve is compatible with Hyundai R305, R215, R225, and R385 series excavators. It is a crucial pressure control and protection component on the multi-way distribution valve. Meticulously machined and measured according to original equipment manufacturer (OEM) data, its thread specifications, orifice diameter and distribution, valve core stroke, and rated opening pressure all match the original parts, allowing for direct insert replacement. No grinding or modification of the distribution valve orifice is required during maintenance and assembly, significantly reducing equipment downtime for on-site maintenance.

The valve body is forged from high-quality alloy steel. The valve core mating surfaces undergo a quenching and hardening process, combined with high-precision honing, to precisely control the clearance between the valve core and valve sleeve. This effectively suppresses internal leakage and stably maintains the hydraulic system's set working pressure under high-pressure, high-flow continuous operation conditions. This relief valve has been specifically optimized for the actual operating conditions of this series of machines. The internal pressure regulating spring is made of high-toughness, high-temperature resistant alloy spring steel, which can withstand repeated oil pressure impacts over long periods without easily experiencing elasticity decay or plastic deformation. Even after prolonged use, it can maintain a stable pressure regulation range, avoiding problems such as pressure drift and pressure relief failure. The valve is equipped with high-pressure and oil-corrosion-resistant sealing kits, which can resist long-term corrosion from high-temperature hydraulic oil and effectively prevent oil seepage from the valve body surface and oil leakage due to aging of the sealing rings.
