VOE14548116 14548116 Hydraulic Safety Valve Rotating Motor Pressure Relief Valve PL4809E Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with PL4809E 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

It is compatible with the main overflow valve of excavators, the main control valve pressure control valve, with an alloy steel forged valve body, high-precision ground valve core, reinforced anti-fatigue springs, anti-leakage and anti-shock performance. It can be directly replaced with the original position without modification. It solves the problems of weak digging force of large excavators, pressure drop during hot operation, and pressure drift. The hydraulic bench calibration is factory-issued. It is a maintenance spare part for mining earthwork construction machinery.

After each overflow valve product is completed, it will undergo multi-dimensional professional hydraulic test bench inspections, including high-pressure pressure resistance and shock tests, pressure adjustment range verification, static internal leakage detection, reciprocating opening and closing durability tests, etc. Through multiple levels of screening and elimination of products with pressure drift, excessive leakage, and valve core jamming, the performance of each delivered accessory is guaranteed to be uniform and stable. Replacing with qualified overflow valves can restore the original factory-designed system pressure of the excavator, providing effective overload protection for the main hydraulic pump, distribution valve, cylinder, slewing motor, and traveling motor, avoiding damage to other expensive hydraulic components due to system overpressure shock, reducing subsequent high-cost maintenance expenses, and enabling large-tonnage excavators to regain strong and stable working capabilities.
