AAK Hydraulic Cartridge Pressure Control Valve with 3 Unique Structures

Divyesh is from a hydraulic equipment manufacturing company in Pakistan, and
has 3 years of procurement experience smoothly. In the second half of last
year, their ultra-high pressure forging press was complained by customers that
the equipment was shaking. After checking, it was found that the hydraulic
cartridge pressure control valve was abnormal and difficult to adjust the
pressure, resulting in large system pressure fluctuations and equipment jitter.
The original manufacturer of the hydraulic cartridge pressure control valve
tried to improve it, but the effect was general. The trouble was that there
were more and more similar complaints. Divyesh had a very big headache.

Divyesh found AAK on Google and stayed on AAK hydraulic valve website for more
than 10 minutes. Perhaps AAK customer cases of optimizing the hydraulic valve
stimulated him and he sent us an email asking:
1. Can AAK make the pressure adjustment of hydraulic cartridge pressure control
valve convenient?
2. How does AAK control the pressure fluctuation of hydraulic cartridge
pressure control valves?
3. How long does AAK need to optimize the original hydraulic cartridge pressure
control valve?

After communication, I learned about Divyesh's dilemma. According to his
original drawings and the schematic diagram of the hydraulic system of the
ultra-high pressure forging press, AAK engineers found that the problem could
be solved by optimizing the structure of the original hydraulic cartridge
pressure control valve. After 35 days, AAK sent 12 samples of hydraulic
cartridge pressure control valves.

3 months later, Divyesh informed by email that AAK hydraulic cartridge pressure
control valve had been used for 3 months, the customer had no complaints about
the forging press shaking. AAK hydraulic cartridge pressure control valve has
stable pressure control and convenient pressure regulation, and their engineers
are very satisfied. AAK hydraulic cartridge pressure control valve is mainly
composed of valve body, booster valve spool, external control valve spool and
spring. Our engineers have made 3 unique structures for the original hydraulic
cartridge pressure control valve, which most hydraulic cartridge valve
manufacturers may not expect.

1. The booster valve spool is T-shaped, and the area of one end connected with
the spring is twice that of the lower end. The valve spool is equipped with a
damping hole extending from the load end to the spring end. The internal
pressure on one side of the spring is lower than the inlet pressure, that is, a
smaller pressure is used to control a larger pressure, which plays the role of
boosting, and the pressure adjustment is convenient.

2. The external control valve spool is connected by a pipeline at one side of
the spring. The valve spool is I-shaped and is equipped with a T-shaped damping
hole, which can make the oil in the compression part press out of the valve
body, effectively maintaining the stability of the external control valve
spool.

3. On the same side of the valve body of the hydraulic cartridge pressure
control valve, there are oil inlet holes and oil outlet holes. The oil inlet
holes are connected through pipelines. The valve body is equipped with a
connection hole at the end of the oil outlet hole. When the load oil pressure
is too large, the upper limit of the oil pressure balance can be carried out to
meet the working condition requirements under ultra-high pressure.

AAK hydraulic cartridge pressure control valve, high pressure and large flow
are also stable, you can also have a small try!
