AAK Hydraulic Directional Valve, 7 top 500 enterprises in use!

Under the pressure and flow conditions, AAK hydraulic valve effectively
controls the sealing ring of each hydraulic valve, so it always ensures that
the flow parameters in the hydraulic directional valve system are at the normal
value. Only a small detail of the sealing ring has made the reputation of AAK
hydraulic valve exceed that of many domestic and foreign peers. I will not
modest about this.

Many hydraulic valve manufacturers are used to domestic sales and are used to
dogmatic production. Maybe they can copy the production process of their peers
and continue to use some traditional technologies, but they may be helpless on
the details or hidden problems of some spare parts.

Leo, an old customer, suddenly sent me 3 samples of hydraulic directional valve
some time ago. I didn't receive any email about these samples of hydraulic
directional valve in advance. So I thought Leo asked us to offer a quotation.

After receiving the hydraulic directional valve samples, I asked him by e-mail
how many quantities he needs and what scenario this hydraulic directional valve
will be used, then I would give him the plan of this hydraulic directional
valve. However, Leo didn't need my quotation, just let me judge the quality of
these hydraulic directional valves. Sending samples to let me just see the
quality without doing other actions. This was the first time I had met.

After testing these hydraulic directional valve samples, AAK HYDRAULIC VALVE
technical team found the overall quality was good. The only hidden danger was
that the flow parameters of one of the hydraulic directional valves were a
little unstable, which should be adjustable in use. I directly told Leo that
these hydraulic directional valves were qualified, but he should pay attention
to flow adjustment during use. Leo's email reply surprised me again. Leo said
that no wonder he stumbled in purchasing these hydraulic directional valves.
Even AAK HYDRAULIC VALVE couldn't find problems with these hydraulic
directional valves.

I angrily asked the technical team to test these hydraulic directional valves
again and simulate the use scenario of Leo's hydraulic directional valve under
the pressurization and flow scenario. The test report came out soon. There were
problems with the sealing rings of these hydraulic directional valves. Leo was
relieved when he learned of the result and found the root of the problem. 30%
of the hydraulic directional valves he purchased this time had the problem of
flow parameters lower than the standard parameter values required by customers.
His hydraulic valve manufacturer had been unable to find the root cause of the
problem. He never thought it was caused by the mismatch of sealing rings. The
traditional nitrile rubber sealing rings were not suitable for hydraulic
scenes.

I told Leo that nearly 90% of the domestic hydraulic valve manufacturers use
either silicone sealing rings or nitrile rubber sealing rings. They rarely
think about different media, different hydraulic scenes, and adjust the
appropriate sealing rings according to the media. They just follow the market
and use what other people use. We AAK HYDRAULIC VALVE, as early as 5 years ago,
had conducted material analysis for this technical pain point. After
comparison, we specified different parameter requirements, different media and
different scenarios to correspond to different material sealing rings. For
example, the sealing performance and stability of fluororubber sealing ring are
most suitable for the hydraulic directional valve required by Leo’s customer.

AAK hydraulic directional valve has details and targeted technology. You can
