For the Hydraulic Cartridge Relief Valve with 3 requirements, AAK got a big order 3 months later

The local Israeli manufacturer was not willing to take risk to develop the hydraulic cartridge relief valve due to small size, and gave it up. After taking over, AAK made 3 improvements in the structure of the hydraulic cartridge relief valve, met the 3 requirements: 450bar high pressure resistance, 500L/min large flow, small pressure loss, and small volume.

Vaughan is from Israel, and they mainly focus on hydraulic equipment in the military market. At the beginning of last year, they customized a hydraulic power unit, which needs to have a pressure resistance of 450bar, the flow controlled by the hydraulic cartridge relief valve in the system exceeds 500L/min, with small pressure loss and small volume. He contacted a local hydraulic relief valve manufacturer to try the sample. The manufacturer reported that there was no problem with the functional requirements, but the size was too small and the risk was high.
