AAK Hydraulic Flow Control Cartridge Valve Knob Unique Skills

Bauer is from Brazil, and has purchased hydraulic cartridge valves from AAK for
3 years. A batch of 70 pcs hydraulic flow control cartridge valves had to ship
before CNY, due to the epidemic situation, AAK workshop stopped production for
11 days, resulting in the batch of hydraulic flow control cartridge valves not
being shipped on time. Bauer understood the situation, because this guy also
knew that I was doing my best. It was finally shipped last week, and Bauer was
relieved, and can hand over the goods to the customer.

In the middle of December last year, Bauer wanted to customize 70 hydraulic
flow control cartridge valves. The adjusting knob must be durable and easy to
operate. I made fun of him: Did you encounter problem so that you think of AAK
cartridge valve? He told me that these hydraulic flow control cartridge valves
were purchased from a local cartridge valve manufacturer in Brazil. During the
daily equipment maintenance, their hydraulic cylinder customer found that the
knob of the hydraulic flow control cartridge valve torque was large, difficult
to turn, and inconvenient. The manufacturer of the original hydraulic flow
control cartridge valve reported that only the knob of this structure could be
used, otherwise it would not be durable. Bauer didn't believe it, so he came to
me.

AAK engineer disassembled the structure of the original hydraulic flow control
cartridge valve, combined with the working conditions of the hydraulic
cylinder, and found that the original hydraulic flow control cartridge valve
knob can be replaced by a new structure. Bauer asked me to arrange production
immediately, and needed to ship before CNY, which means it would have only 30+
days to reprogram and produce 70 hydraulic flow control cartridge valves. I
told him that I would go all out, if without accident, it could be shipped
before CNY.

AAK hydraulic flow control cartridge valve knob system includes positioning
rod, adjusting handle, positioning rod adjusting screw and adjusting screw
seat. The upper end of the adjusting screw seat is provided with a screw hole
that is suitable for the thread of the adjusting screw of the positioning rod,
and the upper end of the adjusting screw of the positioning rod is fixedly
connected with the handle. This structure is completely different from the
concept of the Brazilian cartridge valve manufacturer. It is not only easy to
operate, but also more durable.

1.Between the lower end of the positioning rod adjusting screw and the upper
end of the valve opening positioning rod, there is an intermediate transition
adjustment shaft, and the lower end of the intermediate transition adjustment
shaft and the upper end are also provided with a step shaft.

2. The lower end of the adjusting screw seat is equipped with an adaptive
adjusting shaft positioning hole. The valve opening positioning rod is a ladder
rod with the upper end diameter greater than the lower end diameter. The upper
end of the ladder rod is equipped with an adaptive adjusting shaft connecting
hole.

3. The valve cover is provided with an upper round hole and a lower round hole
which are respectively suitable for the reciprocating dynamic seal at the upper
and lower ends of the positioning rod. The upper end of the positioning rod,
the lower end of the adjusting screw seat, the side of the intermediate
transition adjusting shaft, and the corresponding hole surface on the valve
cover form a pressure relief oil chamber of the adjusting screw. The valve
cover is equipped with a guide oil passage. The positioning rod is located
below the connecting hole of the adjusting shaft, and is equipped with a liquid
return oil passage.
