Remanufacturing and Benefits Analysis of Construction Machinery Hydraulic Valves

Abstract

Lots of hydraulic valves lose efficacy every year because of the complex mechanism of construction machinery, bad working conditions and changeable objects. These invalid hydraulic valves were melted down in the oven and then reused. However, the additional value of valves is wasted, and it will consume a lot of resources. The remanufacturing industry, which is becoming more and more mature, can solve this problem. The hydraulic valve can be remanufactured by recollection and using professional technology. Here is an introduction of failure modes and remanufacturing process of hydraulic valve, and also a deep analysis to the benefits of economy, resources and environment. It turned out that remanufacturing can restore the function of the invalid hydraulic valve and shorten the production cycle. It also can save costs by 55%, save resources by 85% and save material by 90%.
