| Message: | Torsten is from the Netherlands. As an old purchaser, he is very handy in the hydraulic industry. Unexpectedly, he fell on a hydraulic valve block with 24 deep holes and large holes. In the second half of last year, his company developed a large-scale hydraulic windlass for ships. The hydraulic valve block used was sampled from a hydraulic valve block manufacturer in the Netherlands, but the machine running test was not smooth. After the equipment has been operated for 8 hours, there is leakage at the installation hole of the hydraulic valve block. After eliminating the suspected quality of the hydraulic cartridge valves, the engineer inspected the installation hole of the hydraulic valve block and found that the center position of the hole was offset.
