| Message: | AAK Hydraulic Valve Block Has Unique Anti-rust Technology, Russian Customer Tried A Small Order
AAK hydraulic valve has a proprietary valve block anti-rust treatment technology. A special coating with a thickness of 0.02 ~ 0.03 mm is plated on the surface of the hydraulic valve block. The coating has excellent adsorption, is not easy to fall off and has a bright appearance. On this point alone, it has crushed most of its peers. After several email communications, Russian customer resolutely placed an order with AAK.
Due to the limitation of process, most hydraulic valve factories adopt surface painting or conventional electroplating for the anti-rust treatment of the hydraulic valve block surface. Such anti-rust treatment on the surface of the valve block will cause problems in the routine maintenance or repair of the hydraulic valve in the future. It is mainly reflected in that the valve block is easy to be scratched, causing corrosion and increasing system pollution. Besides, falling paint and other sundries are also easy to enter the valve block channel and bring pollutants directly to the system, resulting in secondary pollution of the system and accidents. The trouble is that it is generally difficult to find the problem of rust prevention on the surface of these valve blocks in the short term.
Anatoly, a Russian hydraulic customer, purchased a batch of hydraulic valve blocks in March from a factory. There were no problems in the preliminary test and final inspection. However, he continued to receive feedback from consumers in the last month. After setting up and debugging, the surface of the valve block fell off paint, rusted, and even there is pollution inside the system. According to the statistics of the information received, among the 200 products purchased, there are nearly 100 products in this situation now, and only 100 are still on sale. Anatoly found something wrong and immediately asked to suspend the sales of the remaining products.
