| Message: | Beacan is from Egypt and has been purchased from hydraulic cartridge valve manufacturers in China for 1 year. In December of last year, a batch of their hydraulic pilot-operated cartridge relief valves was complained of large pressure fluctuations by customer. The original manufacturer of the hydraulic cartridge relief valve said that it was necessary to optimize the internal structure, but it was uncertain. Beacan contacted other hydraulic cartridge valve manufacturers, but there was no solution. Beacan was worried. |
