AAK Hydraulic Threaded Cartridge Valve Helped 3 Departments of Caterpillar
Early last month, I saw an email from Mark, the purchasing manager of hydraulic

system of Caterpillar, an old friend of ours. The subject of the email is "I
need help from AAK, I believe". After reading the email about hydraulic
threaded cartridge valve, I understood Mark's embarrassment.
A small less-known excavator designed by them at the beginning of this year was
not smooth in the commissioning process, the response of the excavation part
was slow and the power was not enough. After testing, the technical department
found that the measured value of the maximum overflow pressure was lower than
the specified value, so it was determined that there was a problem with the
hydraulic threaded cartridge valve. Mark communicated with the original
hydraulic valve supplier. The supplier mentioned that the hydraulic threaded
cartridge valve was sampled according to their company's drawings, and all
parameter tests were up to standard. The supplier told the fact. He then could
only patiently communicate with the design department to see how to modify the
hydraulic threaded cartridge valve design, but the design Department said that
there was a problem with the installation of the technical team. The company's
design and technology departments prevaricate with each other and Mark are
caught in the middle, which is very embarrassing and time is also being wasted.
If the boss is angry one day, it is estimated that all 3 parties will be
AAK HYDRAULIC VALVE has always been Mark's most trusted supplier of hydraulic
valves. I asked Mark to send us the original design drawings of the hydraulic
threaded cartridge valve and the working condition requirements of existing
equipment, as well as the problems and data encountered in commissioning.
3 days later, we replied to Mark that we have a new design scheme, and we are
90% sure that we can make the hydraulic threaded cartridge valve that meet the
equipment requirements, but it will take 2-3 weeks. On the 3rd day after
receiving our sample of the hydraulic threaded cartridge valve, Mark happily
informed us that the technical department tested AAK hydraulic threaded
cartridge valve, the equipment commissioning was smooth, and the reaction and
power of the excavation part were normal. The technical department said that
the large goods of this hydraulic threaded cartridge valve can only come from
AAK, and other hydraulic valve manufacturers are unreliable.
Caterpillar designers are also curious about how AAK HYDRAULIC VALVE redesigns
this hydraulic threaded cartridge valve? AAK engineering team tried 30 times to
design, sampling and make adjustment to find a breakthrough. A sealing ring
groove is arranged between the oil replenishment outlet and the oil
replenishment inlet of the oil replenishment valve seat of the hydraulic
threaded cartridge valve. The oil replenishment valve seat is made into a
cartridge valve body, a sealing ring is installed between the overflow valve
seat and the rear end hole of the oil replenishment valve spool, and a spring
with a set oil replenishment pressure difference is placed. For the hydraulic
threaded cartridge valve with this structure, the excessive pressure oil can
directly push the overflow valve spool from the oil replenishment outlet and
automatically relieve the pressure. The whole overflow action is more direct
and sensitive than before, and the pressure regulation response is fast, which
protects the whole pressure system and the pressure is more stable.
After knowing the whole process, the boss praised mark, rewarded him with an
extra week's holiday, and suggested him to increase cooperation with AAK
HYDRAULIC VALVE. His colleagues in the technical department and design
department also admire him for taking the initiative to solve the dilemma of
the hydraulic threaded cartridge valve, and Mark's prestige in the company is
getting higher and higher.
AAK is a designated hydraulic threaded cartridge valve manufacturer of
Caterpillar. You can also have a small try.
