Product Specification

GVO 14514691 Main Control Valve Pressure Relief Valve Regeneration Valve EC210B EC240B EC210D EC240 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 series relief valve is specifically designed for the hydraulic systems of EC210B, EC240B, EC210D, and EC240 excavators. As a core pressure protection component in the main hydraulic control circuit, it directly controls the main pump output pressure, effectively stabilizing the overall hydraulic workload.

The product adopts a high-precision integrated valve core structure, precisely machined to match the original vehicle's valve bore dimensions. It allows for direct replacement of original parts without requiring valve body modifications. Made from high-quality alloy steel that has undergone quenching and cryogenic tempering, the valve core mating surfaces undergo high-precision honing, ensuring precise clearance control and extremely low leakage under high-pressure conditions. This maintains the system's preset pressure, preventing common excavator malfunctions such as stalling, weak movement, insufficient pressure, and slow boom lifting. It perfectly adapts to the pressure regulation needs of different hydraulic pump systems in B-series and D-series models.

The internal spring is made of high-temperature resistant alloy spring steel, resistant to fatigue and deformation under continuous pressure, ensuring stable and long-lasting pressure regulation performance without pressure drift or pressure relief failure after a period of use. The valve sleeve sealing position is machined to standard specifications and equipped with high-pressure and aging-resistant sealing components to resist high-temperature corrosion of hydraulic oil and reduce oil leakage.
