| Message: | Early March this year, Austin from Canada left a message on AAK website: AAK hydraulic valves have been used in aviation field, can you produce hydraulic relief valves with the valve body produced by nickel titanium alloy? For similar messages, I basically reply that if there is a need, I will directly sampling the hydraulic relief valves. Whether it can meet the standard is not determined by mouth, but by data. After communication, it was learned that their company has a power unit used in the aviation hydraulic system, and the customer requires that the test run be completed within 3 months. Austin contacted an old supplier of hydraulic relief valves with the best quality, and the supplier promised to deliver 20 samples of high-precision hydraulic relief valves within 40 days. After 20 days, the manufacturer of the hydraulic relief valves can't bear it. In particular, the valve body of the hydraulic relief valves is made of nickel titanium alloy. During processing, the cutting tools were changed for 5 times, and 80% of the products were still scrapped.
Austin had to find a new manufacturer of hydraulic relief valves. He contacted some new manufacturers in a few days, they either have no confidence in the hydraulic relief valves used in the aviation field, or no reply at all. Austin saw in Google that AAK hydraulic valve supplied to military enterprises and aerospace equipment, and realized that maybe AAK can help solve the dilemma of hydraulic relief valves. According to the hydraulic relief valve drawings and working condition requirements emailed by Justin, AAK engineers found that this hydraulic relief valve is just similar to the one supplied to Russian customer last year. The difference is the valve hole size. It only needs to make small modifications to the process procedure, and 20 hydraulic relief valve samples are sent out after 15 days.
