Product Specification

SA7242-11580 VOE14524582 SA8230-12520 Main Relief Valve Pressure Relief Valve Hydraulic Safety Valve EC290 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 EC290 relief valve is a core pressure control component of the EC290 excavator's hydraulic system. The valve body is made of high-strength alloy steel, precision CNC machined and heat-treated, with the valve core precisely ground and matched.

The optimized internal valve core structure enhances its resistance to impurities, reducing valve jamming caused by hydraulic oil contaminants. Imported seals are oil- and high-temperature resistant, preventing aging and leakage even after long-term operation. It effectively improves common problems such as weak equipment movement, stalling, system pressure fluctuations, and insufficient digging force. Its sensitive opening and closing response and minimal pressure drift significantly reduce the probability of excavator hydraulic system failures.

The threads, mounting outer diameter, and port position are identical to the original parts, allowing for direct installation without modification. Shock-resistant and fatigue-resistant, it continuously and stably maintains the hydraulic circuit's set pressure, making it a high-performance, cost-effective replacement part for EC290 repairs.
