AAK Hydraulic Cartridge Counterbalance Valve 2 Advantages

Harold is from Peru and specializes in hydraulic logistics equipment. In the
second half of last year, they developed a lift that experienced shaking and
impact when the load was lowered. Their engineer determined that the hydraulic
cartridge counterbalance valve was not satisfactory and requested the original
manufacturer to improve its function, but the other party gave up. Harold spent
3 months with this hydraulic counterbalance cartridge valve manufacturer from
inquiry to sample, which made him very discouraged.

Harold found AAK hydraulic cartridge valves on Google search and noticed that
AAK has introduced some customer cases about the solution for difficult and
complex hydraulic counterbalance valves. He asked via email: Can AAK hydraulic
counterbalance valves solve system shaking and impact phenomena? After
communication, it was learned that he had encountered difficulties in
purchasing hydraulic counterbalance valves. In fact, this is a common problem,
which is likely caused by sudden changes in the flow area of the valve port,
resulting in low-frequency vibration and impact. Based on his original anatomy,
it's the same as what I guessed. As long as the hydraulic counterbalance valve
is set with a buffering function, it can be solved. After 50 days, AAK sent 20
samples of hydraulic counterbalance valves.

Harold, 3 months after the sample of the hydraulic counterbalance valve was
sent out, brought me good news. This morning, when I opened my email, I saw his
PO for 200 hydraulic counterbalance valves. Their engineers are very satisfied
with the buffering function of AAK hydraulic counterbalance valve, and the load
shedding is stable, without shaking or impact. Just like this, the additional
function of AAK hydraulic counterbalance valve brings 2 advantages to his
equipment. AAK does this by creating grooves on the main valve spool of the
hydraulic counterbalance valve to accurately control the flow area. When the
load drops, it is controlled by a gentle throttle and can also quickly buffer
the impact pressure.

1. The main valve body of the AAK hydraulic counterbalance valve has a fixed
first valve seat, and one end of the main valve spool is connected to the first
valve seat, which slides and fits with the main valve body. The inner chamber
of the main valve body is divided into the first and second chambers connected
to the oil inlet, as well as the control chamber.

2. The second chamber is equipped with a second valve seat and elastic
components. When the oil enters the oil inlet, the oil pushes open the second
valve seat and flows to the oil outlet. The elastic component presses the steel
ball onto the flow channel port inside the main valve spool through the spring
seat.

3. There are multiple U-shaped grooves along the axial direction on the
circumferential surface of the main valve spool, and the key lies in the depth,
width, and distance between the grooves and the steel ball.

AAK hydraulic cartridge counterbalance valve, has 1 additional function
compared to its peers, and you can also give it a try!
