| Message: | Castel is from Saudi Arabia, and their company mainly sells oil mining machinery. At the beginning of last year, one of their hydraulic platforms was complained, and the equipment went on strike 8 - 9 months later. After checking, it was found that the shoulder and pin hole of the hydraulic cartridge needle valve spool in the system were broken. The hydraulic cartridge needle valve manufacturer advised that the same model of hydraulic cartridge needle valve was supplied to the South American market. Within 1 year, there was no complaint. The manufacturer explained that the brittle fracture of the hydraulic cartridge needle valve spool was caused by the working conditions and working scenarios. The boss was not satisfied with the manufacturer's buck passing, and asked Castel to found a manufacturer whose hydraulic cartridge needle valve can be used for more than 1 year. Based on the requirement of "hydraulic cartridge needle valve can be used in desert with a service life of more than 1 year", Castel started to look for new cartridge valve manufacturers. After 1 week, there was no result. Castel was a little flustered. |
