AAK Hydraulic Cartridge Valve 3 Advantages

Dakshesh is from a hydraulic equipment manufacturing company in India. They
have a batch of high-power hydraulic cylinders and need to customize hydraulic
cartridge valves. Dakshesh chose a local manufacturer that has cooperated for 6
years to make samples. During the equipment commissioning, the hydraulic
cartridge valve has large pressure impact, noise, and the overload overflow
protection action is not sensitive, resulting in the instability of the
hydraulic cylinder. The manufacturer of the hydraulic cartridge valve reported
that these are unavoidable under the working condition of 450 bar high
pressure. Dakshesh contacted more than 10 other hydraulic cartridge valve
manufacturers, but there were no results. The engineer has urged several times,
Dakshesh was in a hurry.

Dakshesh wrote an email to AAK. He introduced himself that one of his hydraulic
cylinder customers suggested him to contact AAK HYDRAULIC VALVE. After
communication, it was learned that one of my old customers in India introduced
AAK to him. Dakshesh encountered the problem of hydraulic thread cartridge
under 450bar working condition. For the hydraulic cartridge valve, under 450
bar high pressure, free of impact and noise, and stable operation, it is a
typical requirement of German HAWE cartridge valves. I told him that this can
be solved completely by HAWE, or AAK. For cartridge valves in the high-pressure
field, AAK benchmarks HAWE, because our engineers have worked in HAWE for more
than 10 years, and have excellent skills in high-pressure. After 35 days, AAK
sent 12 customized samples of hydraulic cartridge valves.

Yesterday, Dakshesh sent an email, wishing the AAK cartridge valve a smooth
start. At the same time, he told me that the hydraulic cylinder with AAK
hydraulic cartridge valve is not only noiseless, but also stable. The high-
power hydraulic cylinder prototype has been delivered to the customer, and he
is confident to get a big order.

AAK hydraulic cartridge valve has low impact, no noise and is stable under high
pressure of 450bar. The key is due to 3 unique structures:

1. The outer cavity of the right end of the hydraulic cartridge valve guide
valve seat is connected with personalized pressure regulating screw and lock
nut. The outer side of the left end of the guide valve seat is connected with
the oil replenishing valve sleeve.

2. The oil make-up valve sleeve is coaxial with the main valve spool and the
main valve piston. The pressure regulating screw is connected with the guide
valve spool, and the two ends of the guide valve spool are respectively located
in the inner cavity of the guide valve seat and the oil make-up valve sleeve.

3. The left end of the guide valve seat and the right end of the main valve
spool are connected with the first spring, and the first spring is connected
with the outside of the seal body. Both the front end of the guide valve seat
and the inside of the main valve piston are equipped with orifices. When high-
pressure oil passes through, the impact is small and there is no noise.

For the optimized AAK hydraulic cartridge valve, the oil inlet of the guide
valve seat is located in the rear hole of the valve body and the oil makeup
valve sleeve, which is equivalent to integrating the guide valve, main valve
and oil makeup valve into the oil makeup valve. In this way, it has the dual
functions of overflow and oil replenishment. High pressure resistance 450bar,
small impact, noiseless and stable.

AAK hydraulic cartridge valve has three advantages under high pressure of
450bar. You can also try it!
