GVO 14610078 Hydraulic Check Valve Pressure Safety Valve Relief Valve EC210B EC210D EC240B EC290B Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with EC210B EC210D EC240B EC290B 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 threaded plug-in type overflow valve is a core hydraulic safety component for the main control multi-way valves of EC210B, EC210D, EC240B, and EC290B excavators. It is assembled inside the valve port of the distribution valve and mainly realizes key functions such as system pressure limitation, overload overflow pressure relief, and hydraulic circuit pressure stabilization. 

The valve body itself is made of high-hardness alloy steel and is formed by a single-piece processing. The valve core and valve sleeve components undergo multiple precise honing and matching grinding processes. The valve port has high precision and can withstand long-term erosion by high-flow high-pressure oil. It effectively resists wear caused by impurities in the hydraulic oil and significantly reduces the probability of valve core sticking, valve port erosion, and internal leakage. 

The entire set of valve components is equipped with high-quality composite sealing components, which have the characteristics of high pressure resistance, anti-aging, and resistance to oil temperature changes. Whether it is the high-temperature working conditions caused by long-term heavy-load operations in summer or the cold machine startup in a low-temperature environment, the sealing components can maintain a stable sealing effect, reducing problems such as system internal leakage and insufficient pressure maintenance caused by sealing failure. The product is of standard plug-in threaded structure. The outer diameter of the valve body, the thread profile, the oil hole position, and the assembly depth are all in line with the original vehicle components. During maintenance and replacement, there is no need to modify or process the distribution valve at all. Simply install it into the valve port to complete the assembly. The disassembly and assembly operations are simple and quick, greatly shortening the downtime for equipment maintenance on the construction site. It highly meets the operational requirements of on-site emergency repair and rapid maintenance by repair shops.
