For hydraulic cartridge flow control valve that HAWE can't handle, AAK changed material for 3 times

Katherine is from a Greek hydraulic equipment manufacturing company. There were several inquiries for hydraulic cartridge flow control valves with AAK before, but there was no cooperation. In the second half of last year, their customer wanted to customize a set of hydraulic power unit used in aviation equipment. The requirements for hydraulic cartridge flow control valve parameters were: performance of 2 million times, valve hole accuracy with 1μm, high pressure resistance 450bar. Their engineer suggested Katherine contact German HAWE, because HAWE is the No 1 in subdivision of high-pressure hydraulic valves. But HAWE had no time to sample.

Her customer introduced a local hydraulic cartridge flow control valve manufacturer in Greece, and Katherine also contacted me. According to above information, I told her directly that we are not sure for success, but our engineers are confident in the sample.
