| Message: | Cemeh comes from Russia, and has been purchasing hydraulic valves smoothly. At the beginning of this year, he was very passive when purchasing a hydraulic pressure control valve that can withstand high pressure of 450bar. Their hydraulic power unit used in the aviation industry requires the use of hydraulic pressure control valves with high precision requirements and high pressure resistance. Cemeh made samples from a hydraulic pressure control valve manufacturer who has been cooperating for 3 years. The equipment has been debugged twice, and when the pressure reaches 450bar, there is a leak in the hydraulic pressure control valve. The original hydraulic valve manufacturer stated that due to the need to withstand high pressure of 450bar, the valve cage material can only be selected from high carbon chromium bearing steel, which has high hardness and is prone to precision errors during processing. Therefore, the original manufacturer gave up. Cemeh contacted other hydraulic valve manufacturers in China but was unsuccessful. |

Is this a real buying request?
