AAK Hydraulic Manifold for Elevators No Worry in 12 months of Use

Eugenia comes from Greece, and has been smooth on purchasing for 5 years.
Unexpectedly, due to a hydraulic manifold, she was in a trouble. At the
beginning of this year, their company developed a hydraulic station for
elevator lifting systems for the first time, which requires hydraulic manifold.
Eugenia chose a manufacturer that has been cooperating for over 3 years to make
samples, and the sample testing went through smoothly. The first batch of 50
hydraulic stations, after 2 months of operation, occasionally experienced
abnormal elevator operation. The after-sales engineer found that there was a
leak in the hydraulic manifold within the system, and some pressure control
cartridge valves have hysteresis in opening and closing. Per the manufacturer
of the hydraulic manifold, it is normal for individual abnormalities and it can
be replaced for free. However, the customer is not satisfied and requested to
ensure that each hydraulic manifold is 100% normal within 12 months. Eugenia
became anxious.

Eugenia found AAK on Google and left a message on AAK website: Can AAK ensure
no abnormalities within 12 months for the hydraulic manifold on the elevator
lifting system hydraulic station? After communication, it was learned that the
manufacturer he placed the order with is not specialized on the production of
the hydraulic manifolds for elevator lifting systems. Eugenia is surprised to
ask, “Does this require a dedicated factory to produce?” I told her that
although the production process of hydraulic manifolds is the same, the testing
process is completely different. I sent him a video of AAK's dedicated
hydraulic manifold testing for elevator lifting system hydraulic stations, and
also included the case of AAK's previous solution for Russian customers on
elevator lifting system hydraulic stations.

The next day, Eugenia sent us the complete hydraulic manifold drawings and the
working principle diagram of the entire hydraulic station. It took less than 1
week for AAK to provide modification suggestions, quotations and receive the PO
for the hydraulic manifolds.

For the hydraulic manifolds used on the hydraulic station of the elevator
lifting system, AAK not only considers the function and stability of hydraulic
manifolds in material selection and manufacturing accuracy, but also the most
important is the testing. AAK has a self-developed elevator hydraulic station
testing system that directly simulates elevator on-site work. Before shipment,
each hydraulic manifold undergoes functional testing.

Firstly, the system pressure will be set to 31.5Mpa. When the elevator up
button is pressed, the elevator will automatically and smoothly run up to the
designated position and stop. When the elevator down button is pressed, the
elevator will automatically and smoothly descend to a fixed position. The trick
inside this is that the hydraulic manifold has stepless speed regulation, small
reversing impact, and the service life of the hydraulic system is protected.

AAK hydraulic manifold used in elevators, with proprietary testing equipment,
and is safe in 12 months, you can also give it a try!
