AAK Hydraulic Cartridge Counterbalance Valve with 3 Highlights

Amador is from a hydraulic equipment company in Bolivia. Some time ago, he
encountered problems with a hydraulic cartridge counterbalance valve. A
logistics lifting device developed by his company needs to use hydraulic
cartridge counterbalance valves. Amador selected a hydraulic cartridge valve
manufacturer in Ningbo who has cooperated with him for 2 years to test samples.
There was a hidden danger in equipment debugging: when materials rise to a
certain height and stay, they will automatically fall down slightly and shake
with low frequency. The reason is that the balancing capacity of the hydraulic
cartridge counterbalance valve does not match the load. Although the hydraulic
cartridge counterbalance valve has no leakage and no abnormal function, it must
be optimized. The manufacturer had no idea for optimization and gave up. Amador
contacted about more than 10 hydraulic cartridge valve manufacturers, but after
a week, it was fruitless. Amistad became very worried.

When browsing Google, Amador found an AAK article about AAK unique designed
hydraulic cartridge counterbalance valve helped Indian customer solve the
hidden danger of hydraulic lifting device. This is very close to his current
situation. He left us a message:

1. I paid attention to the personalized design of AAK hydraulic cartridge
counterbalance valve, helping Indian customer solve the hidden danger of
hydraulic lifting device.

2. Can AAK solve the hidden danger that the balance capacity of the hydraulic
cartridge counterbalance valve does not match the load?

3. To customize a hydraulic cartridge counterbalance valve that the balance
capacity matching the load, what is the lead time and cost?

I guess that he encountered trouble in purchasing hydraulic cartridge
counterbalance valves. After communication, I learned the above story.
According to the information provided by him, I told him that when the
hydraulic cartridge counterbalance valve works, it mainly depends on generating
a back pressure balanced with the load. When the load weight is small, the
system will produce low-frequency jitter. When the load weight is large, it is
easy to have a little leakage, causing the weight materials to fall slightly.
This model has different problem from that Indian customer, and solution will
be also different. Amador may have seen hope and requested AAK to try samples.
After 35 days, AAK sent 12 hydraulic cartridge counterbalance valves.

3 weeks later, Amador informed us by email that with AAK hydraulic cartridge
counterbalance valves installed, the equipment was debugged smoothly, and the
load did not drop or shake. It will be promoted in the market soon, they are
confident to get a large number of bookings.

1. For this hydraulic cartridge counterbalance valve, AAK adopts a cone valve
structure and is equipped with a regulating rod, which can adjust the area of
the initial orifice to match different flow ranges.

2. It is equipped with a load adaptation mechanism, a strong spring and a weak
spring. The two springs are connected together through the spring seat. The
weak spring in the low pressure section acts, the spring seat in the high
pressure section automatically limits, and the strong spring acts.

3. The valve spool is flexible, controllable and free from load interference.

AAK hydraulic cartridge counterbalance valve, no hidden danger and safe, you
can have a small try!
