Hydraulic Directional Control Valve PC08-30 Higher Accuracy Faster Delivery

Snova is from Russia. A few days ago, she left a message on AAK hydraulic valve
website:
1．Can AAK deliver 500 pcs of hydraulic directional control valves PC08-30
within 35 days?
2. The outer diameter accuracy of the valve cage needs to be higher than
HydraForce standard, as our original system has a higher accuracy setting than
HydraForce.
3. Can we ship first and make payment later?

Upon seeing this message, I estimated that she encountered difficulties in
purchasing the hydraulic directional control valve PC08-30. After
communication, I learned that she had chosen a hydraulic cartridge valve
manufacturer in Ningbo China. In fact, the manufacturing quality of this
manufacturer should not be a problem compared to that of HydraForce PC08-30.
Snova advised that the main issue is the unstable accuracy of the outer
diameter of the valve cage, as their standard is higher than that of HydraForce
PC08-30. Based on the 3 points in her message, I replied that point 1 and 2 are
a challenge, but we are confident in surprising her. Point 3 is impossible, AAK
never does credit business.

Snova mentioned that because the original hydraulic cartridge valve
manufacturer wasted 6 weeks, she must find a manufacturer who is able to
deliver 500 pcs of hydraulic directional control valves PC08-30 within 35 days,
and the outer diameter accuracy of the valve cage needs to be higher than
HydraForce PC08-30 standard. The valve cage that happens to be being processed
in AAK workshop is somewhat similar to PC08-30. I sent her a video to show the
production process. Whether it is precision control or production efficiency,
this video can dispel Snova's concerns.

For precision machining of the outer diameter of the hydraulic directional
control valve cage, especially the precision requirements in 1-2μm, it can be
done by using Japan's Tsugami CNC centerless grinding machine. The biggest
advantage of this equipment is the grinding wheel shaft, which uses Tsugami's
high rigidity dynamic pressure bearings, without any possibility of deviation,
providing guarantee for accuracy without deviation. Before the production of
the hydraulic directional control valve cage, according to the accuracy
requirements of the valve cage, set the system program, adjust the height of
the workbench, ensure that the installation position of the workbench, valve
cage, and the distance and angle between the spindle axis meet the
requirements, which tests the skills of the technician. AAK has also equipped
the device with an automatic turntable. We only need to place the valve cage to
be processed into the turntable. After starting the device, there is no need
for technicians. The centerless grinding and precision machining does not need
manual labor, with an efficiency increase of over 30% and an accuracy 1μm
higher than HydraForce FC08-30.

30 days later, last week, AAK delivered 500 pcs of hydraulic directional
control valves PC08-30. Snova is very happy, at least AAK's production
efficiency is higher than other hydraulic cartridge valve manufacturers in
Ningbo China. I told her that there was no need to worry about the outer
diameter accuracy of the valve cage, as AAK's standard was 1μm higher than the
HydraForce standard.

AAK hydraulic directional control valve, with an efficiency increase of over
30% and an accuracy increase of 1μm, you can also give it a try!
