valves for more than 3 years. His boss trusts him very much. At the beginning
of last year, a number of their hydraulic paper cutters were complained by
customers. The problem was that the hydraulic directional cartridge valve spool
was worn and stuck. His boss was surprised. In the purchasing from AAK for more
than 3 years, there was no quality complaint about the hydraulic directional
cartridge valves. After checking, it was learned that this hydraulic
directional cartridge valve is a standard part of HydraForce. Chaika found a
manufacturer that is 20% cheaper than AAK to place the order. The boss asked
Chaika to re-purchase the hydraulic directional cartridge valves from AAK for
Chaika candidly told us the problems encountered on this hydraulic directional
cartridge valve, and needed the help of AAK, to urgently produce 50 hydraulic
directional cartridge valves within 30 days. After 25 days, AAK successfully
delivered the hydraulic directional cartridge valves.
4 weeks later, Chaika informed that the problem of the equipment being
complained about had been solved. This time, the boss was not happy and the
customer was not satisfied, which made him under great pressure. He thanked me
for solving the problem of the hydraulic directional cartridge valve in time. I
told him that although AAK hydraulic directional cartridge valve is 20% more
expensive, its service life is twice that of its peers, it has stable
manufacturing quality, durable and fault-free, due to the following 3 efforts:
1. In terms of material, AAK hydraulic directional cartridge valve, the spool
is made of 100Cr2 bearing steel, and then targeted heat treatment. Permeating
at 820-830 ° high temperature for 13 hours, then oil quenching, - 60 ° to -
70 ° cryogenic treatment,+150 ° to+160 ° tempering treatment. Not only is
the molecular structure uniform, but also the hardness is increased to HRC68.
The valve spool with good wear resistance and high strength, ensures that the
service life of AAK hydraulic directional cartridge valve is twice that of its
2. In terms of processing, the processing accuracy of AAK hydraulic directional
cartridge valve can reach 0.01~0.3μm by Japan OKK ultra-precision machine
tool. And the production efficiency is more than 30% faster. Under the
operation of our old technician for more than 30 years of experience, the
components processed have no defects.
3. In terms of detection, the German Diatest small micro-pore diameter
measuring instrument is used to check and accurately measure the valve hole of
AAK hydraulic direction cartridge valve, and the measurement can reach 0.1μm.
AAK hydraulic directional cartridge valve, although more expensive by 20%, it
has a service life of 2 times that of other cartridge valve manufacturers in
China. Welcome to have a try!
