Maarten purchased a batch of hydraulic valve blocks some time ago. In the early test, the system parameters were normal. Strangely, 10 days after the hydraulic valve block was started, the hydraulic oil in the system suddenly deteriorated.

Before, Maarten had a certain understanding about us AAK hydraulic valve through some B2B websites, so with a try mentality, he directly emailed us a trial order for 5 hydraulic valve blocks.

Why do more than 10 hydraulic valve manufacturers dare not accept the order of this hydraulic valve block? Because this hydraulic valve block is very special. There are many slender holes in the processing channels intersected by each hydraulic valve block, and the cleaning of iron filings is a cumbersome process. If there is no unique skill, it is difficult to eradicate it 100%. 2 years ago, AAK hydraulic valve also had an order cancelled by customer due to the iron filings of hydraulic valve block not completely eradicated. After that lesson, our technical team spent half a year innovating the production process of hydraulic valve block, and finally AAK hydraulic valve was able to mass produce the hydraulic valve without iron filings 1 year ago.

The reason why AAK hydraulic valve block can remove the residual iron filings that can not be achieved by peers is that after the hydraulic valve block is processed, AAK firstly uses high-temperature alkaline water to cook the hydraulic valve block, so that the iron filings of the hydraulic valve block lose demagnetization, and then uses a small pneumatic grinding wheel to clamp the rotary file to go through the hole, so as to completely eliminate possible flash at the corner. Then, the high-pressure washing machine shall carry out high-pressure washing on the dirt on the inner and outer surfaces of the duct. Finally, the industrial endoscope and cold light source shall be used to check the flash and burr at the corner in the duct.
