Product Description

The GVO excavator relief valve, compatible with DH225-7 JS200 JS260 JS360 JS290 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 DH225-7, JS200, JS260, JS360, and JS290 universal plug-in relief valve is a crucial pressure protection component in the hydraulic system of excavators. It adopts a threaded plug-in structure and is directly installed in the valve body of the distribution valve, undertaking the functions of pressure limitation and overload relief in the entire hydraulic main circuit. It directly determines the system pressure value of the entire machine, controls the digging force, and protects various high-priced hydraulic core components such as the main pump, distribution valve, and motor from damage caused by high-pressure impacts.

The valve core and valve sleeve of this series of relief valves are made of high-strength bearing alloy steel raw materials. They undergo precise deep-hole processing, carburizing and quenching heat treatment, and then undergo high-precision matching grinding. The clearance between the valve core and the valve sleeve is controlled at the micron level, possessing extremely strong shock resistance and wear resistance. It can resist scratches and wear caused by impurities in the hydraulic oil. The internal springs of the entire assembly are made of high-temperature-resistant alloy spring steel wires, and undergo fatigue strengthening treatment. Under long-term repeated relief and high-frequency impact conditions, the spring elasticity is stable, and there is no problem of fatigue attenuation or weak elasticity.
