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.

 

Two months later, Austin informed by email that the commissioning of the equipment was very smooth with the use of AAK hydraulic relief valves. AAK was the only one of more than 10 hydraulic relief valve manufacturers he contacted, who dared to make samples directly and completed the non-standard hydraulic relief valves in 2 weeks. Their engineers were surprised to have such a magical hydraulic relief valve manufacturer.

 

The non-standard hydraulic valves were completed in 2 weeks, which most hydraulic valve manufacturers can't do unless there are similar procedures. AAK has a number of non-standard hydraulic valve procedures. The key reason why AAK hydraulic relief valves can be supplied to military enterprises and aerospace fields is the following 3 points. There may not be a second hydraulic relief valve manufacturer in Ningbo that can meet the 3 points at the same time.

 

1. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control.

 

2. AAK has a high-precision CNC machining center imported from Switzerland and Kennametal combined tool imported from the United States. This tool has the best cutting ability for NiTi alloy with very high toughness and strength, and has high advantages in life, performance, efficiency and stability.

 

3. AAK test equipment has 5 pressure test benches that can operate independently of each other, and each test area is equipped with professional inspectors, so as to ensure that each hydraulic relief valve is qualified before shipment.

 

AAK high precision hydraulic relief valves can be used in aviation hydraulic system. You can also have a small try!
