In the intersecting processing channels of the hydraulic valve block, iron filings are easy to remain, especially in the slender hole, which is difficult to clean. These fine iron filings are easy to enter the system and cause pollution, resulting in paralysis of the hydraulic system. The eradication of iron filings is a cumbersome process. In order to save costs, many hydraulic valve manufacturers will save processes as long as the hydraulic valve has no problems in the short term. It is a common problem of this industry, less than 10% of manufacturers are willing to make efforts to improve this detail, causing many customers to be cheated.

We are not sure how he found our AAK hydraulic valve. After receiving his email, we replied how we eradicated the residual iron filings in valve block. 6 years ago, we also failed the inspection due to the residual iron filings in the valve block. It took us half a year to explore a set of methods that could completely eradicate the residual iron filings in the valve block:

1.Cook with high-temperature alkaline water to make the iron filings in the valve block lose their magnetism.

2.Hold the rotary file with an electric or pneumatic small grinding wheel, and clean the flash and burr at the corner of the hole channel with a round file for deep holes to achieve smooth connection.

3.Use compressed air and high-pressure washing machine to wash the dirt on the inner and outer surfaces of the duct under high pressure.

4.Use industrial endoscope and cold light source to check the flash and burr at the corner in the duct. If any, flush it point-to-point under high pressure until the iron filings in the valve block are completely eradicated.

5.Clean the residual water and oil in the duct with white silk cloth to ensure that the valve block is clean and free of any residue.
