Message: | solved Tunesi's problem
Tunesi from Bulgaria, has been tortured by a hydraulic cartridge relief valve with 1μm accuracy spool for 3 months. At the beginning of this year, they developed a set of hydraulic manifold that requires the use of hydraulic cartridge relief valves, with high accuracy requirements, especially for valve spool that need to be controlled within 1μm. Tunesi chose an old hydraulic cartridge valve manufacturer in China to make samples. It took 3 months. Every time, among the 10 pcs of hydraulic cartridge relief valve testing samples, there were always several valve spools did not meet the standards. The original manufacturer gave up. The newly developed hydraulic manifold has not been successful due to poor procurement of hydraulic cartridge relief valves, and Tunesi is very annoyed.
