9080500 4378662 Travel Relief Valve Pressure Relief Valve Safety Valve EX120-1 ZX110-3 ZX120-3 EX120-3 EX120 -5 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with EX120-1 ZX110-3 ZX120-3 EX120-3 EX120 -5 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 overflow valve, designed for use with EX120-1, ZX110-3, and ZX120-3 excavators, is the main pressure safety valve at the core of the distribution valve assembly. It is also known in the maintenance field as the main gun, responsible for controlling the maximum working pressure of the entire hydraulic system. It directly determines the digging force, smoothness of movement, and safety of the hydraulic circuit of the excavator.

The valve body base material is made of high-quality and high-strength alloy steel. It is formed by a precision CNC lathe. The core components such as the valve core and valve seat undergo quenching and heat treatment as well as high-precision mirror polishing processes, which enhance the surface hardness of the parts and increase their resistance to wear and tear. This can effectively prevent abrasive wear caused by internal impurities in the hydraulic oil and reduce the occurrence of valve core sticking and seal surface abrasion. The valve is equipped with high-pressure-resistant and aging-resistant high-quality sealing components, which can adapt to the oil temperature fluctuations caused by the long-term continuous operation of medium-sized excavators. In repeated pressure shock conditions, it can effectively prevent external oil leakage, internal pressure loss, and pressure fluctuation problems.
