AAK Hydraulic Flow Control Valve 3 major advantages, recognized by Yagmur

Yagmur is from Türkiye and mainly purchases hydraulic cartridge valve standard
parts from Ningbo. Recently, they developed a hydraulic drilling equipment that
uses hydraulic flow control valves that are modeled after HydraForce standard
parts, and purchased from a hydraulic valve manufacturer in Ningbo. During
equipment debugging, it was found that the flow rate of the hydraulic flow
control valve was unstable, and the leakage rate did not match the hydraulic
system. The original hydraulic flow control valve manufacturer stated that this
is a replica of HydraForce and is unwilling to optimize its function for
several hydraulic flow control valve samples. Yagmur checked with several other
hydraulic valve manufacturers, but they were not interested. Yamour was very
anxious.

The original hydraulic flow control valve manufacturer introduced AAK to
Yagmur. After communication, it was learned that her requirements for this
model include low leakage and high precision requirements for valve holes.
Based on the hydraulic system schematic provided by her and the industry model
code of the HydraForce hydraulic flow control valve, I recommended a ready-made
sample to her. As long as the external dimensions meet his manifold
requirements, it can solve the problem she is currently facing.

2 weeks after the sample was sent out, Yagmur informed via email that the
drilling equipment was successfully debugged. The low leakage of AAK hydraulic
flow control valve meets their system requirements, especially the flow control
function that they are very satisfied with. I told her that for this AAK
hydraulic flow control valve, we have 3 major advantages:

1. The internal leakage of AAK hydraulic flow control valve is 5 drops/min,
while most peers can only achieve 8-10 drops/min.

2. The hole accuracy of AAK hydraulic flow control valve can reach IT6-IT7
level, and the surface roughness can reach Ra0.2-0.025μm.

3. The AAK hydraulic flow control valve function fully aligns with the
standard parts of HydraForce, and there are probably no more than 3
manufacturers in Ningbo to meet it.

The vast majority of hydraulic flow control valve manufacturers in the industry
do not use forming cutters for machining small quantities of hydraulic flow
control valves, but use CNC instead to process according to dimensional
requirements. The result of this machining is an accuracy of 0.03mm and a
positional tolerance of 0.02mm. The AAK hydraulic flow control valve is
processed with forming tools, and the dimensional accuracy of the valve hole
after processing reaches 0.01mm, with a positional tolerance within 0.007mm. At
the same time, AAK has its own standards for tool selection, with hardness of
HRA90 alloy material, heat resistance of 900 ℃, valve hole accuracy of IT6-IT7
level, surface roughness of Ra0.2-0.025μm, and tool life is 30 times higher
than ordinary alloy steel.

AAK hydraulic flow control valve, has 3 major advantages, and its functions are
completely up to standard with HydraForce. You can also give it a try.
