AAK Hydraulic Pressure Control Cartridge Valve with 100% load holding, and solved Kadin's problem

Kadin is from Brazil. I know that he has purchased hydraulic cartridge valves from Ningbo for at least 2 years. The peers joked that his bargain just like cutting vegetables. But a batch of hydraulic pressure control cartridge valves made him suffer. The reason may be that the price was too low. In the second half of last year, they received feedback from customer that the excavator they sold, the stick and boom will fall a short distance after stop working. Their engineers judged that the load holding function of the hydraulic pressure control cartridge valve in the system was abnormal. The original manufacturer of the hydraulic pressure control cartridge valve said that it is too difficult to optimize the function due to its price. Kadin contacted other cartridge valve manufacturers and asked that the load holding function should be 100% guaranteed, and there was no result after a week.
