Product Description

The GVO excavator relief valve, compatible with EX100-1 EX100-2 EX100-3 EX120-1 EX120-2  EX120-3 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

Suitable for excavator relief valves, distribution valve main relief valve, precision processing of alloy steel, calibration of pressure on test bench, sensitive pressure relief, improvement of weak operation of the vehicle when being stalled and abnormal relief noise. The original vehicle size can be directly replaced. Maintenance parts for older medium-sized excavators. 

Each relief valve is tested and calibrated on the hydraulic test bench before leaving the factory. The parameters are in line with the original factory standards, and the valve core has sensitive and precise opening and closing response. When sudden high pressure occurs during digging or lifting the arm, the valve component can quickly open to relieve pressure. After the pressure returns to the normal value, it will quickly close and lock the pressure. This can effectively solve common faults such as the equipment being stalled, slow operation, weak compound action, abnormal relief noise, unstable system pressure, etc. It can restore the equipment's working power, reduce abnormal wear of the hydraulic system, and reduce subsequent large-scale maintenance costs.
