Message: | Sven from Sweden has been purchasing from hydraulic cartridge valve manufacturers in Europe for over a year. At the beginning of this year, his boss requested him to try purchasing from hydraulic cartridge valve manufacturers in China. Unexpectedly, the first time he purchased a hydraulic cartridge pressure control valve, problem occurred. The hydraulic cartridge pressure control valve purchased from the original hydraulic cartridge valve manufacturer has a lifespan of only 3-4 months, and the root cause is leakage at the connection between the valve cage and valve body. The original manufacturer blamed the cold climate for accelerating thread corrosion and causing leakage, which made Sven very helpless. |
