| Message: | Connor is a purchaser from a Russian hydraulic company. There has never been oil leakage due to sealing in his previous purchases of hydraulic valve blocks. Some time ago, a rated pressure up to 450bar hydraulic valve block let him suffer due to the oil leakage of the hydraulic valve block. He communicated with the original manufacturer for many times and debugged for 3 times, but the oil leakage problem still cannot be solved. He then asked his other hydraulic valve block suppliers, they all suggested Connor giving up, because the current sealing technology cannot meet the pressure rating of 450bar hydraulic valve block.
Connor also communicated with some new hydraulic valve block manufacturers online, and gradually understood the shortage of sealing technology. The 90% of hydraulic valve block manufacturers use the conventional sealing method of hexagon socket plug and sealing combination gasket, which is suitable for hydraulic valve blocks with rated pressure of 50-350bar only. For any over 350bar, this sealing method does not work and they have to give up.
Can the sealing problem on a hydraulic valve block with 450bar rated pressure really not be solved? Connor still didn't give up. He found AAK hydraulic valve on B2B and came across an article about AAK hydraulic valve block using Swiss sealing technology to solve the oil leakage of hydraulic valve block. He left a message on our website: can you really solve the problem of oil leakage of hydraulic valve block with rated pressure above 450bar? Seeing this message, I realized that he should have been cheated by other manufacturers before, so he doesn't believe in the new hydraulic valve block manufacturers easily. We replied to him, no matter how much we said, maybe you don't believe it. Simply put, you directly order 1pc of hydraulic valve block according to your drawing. If the hydraulic valve block produced by AAK still leaks oil, we will directly refund you the fee of this testing order. |
