| Message: | Vadim is from the Netherlands and has been engaged in procurement in a hydraulic equipment company for 3 years. Some time ago, they encountered a complaint about the hydraulic support they sold. The hydraulic column was bent. This has never happened before. The engineer was surprised. After field analysis, the problem was that the maximum unloading flow of the hydraulic cartridge pressure control valve was too small to realize rapid unloading, which affected the hydraulic column. The original manufacturer of the hydraulic cartridge pressure control valve tried to modify it once, but it was ineffective. Vadim contacted more than 10 cartridge valve manufacturers, but they couldn't make hydraulic cartridge pressure control valves with instantaneous unloading flow of 10000lpm. Vadim was worried. |
