GVO 4612825 Excavator ZX870 EX1100-3 EX1200-5 Auxiliary Relief Valve Control Valve Hydraulic Safety Valve

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 Hitachi ZX870, EX1100-3, and EX1200-5 ultra-large excavators and is a core pressure protection component of the hydraulic multi-way valve. The valve body is made of high-strength alloy steel, strengthened by heat treatment and high-precision honing. The valve core is precision-matched and ground, allowing for accurate control of hydraulic circuit oil pressure.

The optimized valve core structure enhances its resistance to impurities, reducing valve jamming caused by hydraulic oil contaminants. Equipped with high-temperature and low-temperature resistant, high-quality seals, it is less prone to oil leakage and pressure loss during prolonged continuous operation. It effectively improves common faults such as weak digging power, engine stalling and high temperature, system pressure fluctuations, and sluggish operation. Its sensitive opening and closing response and stable pressure during long-term operation effectively reduce major component maintenance costs.
