| Message: | Adam, an old customer of AAK Hydraulic Valve, asked me to copy 2 hydraulic cartridge valve samples for exhibition some time ago. After receiving the samples of cartridge valves, I was a little surprised that the surface of the valve body was not heat treated, just the polished low carbon steel raw material. I double checked with him, is it still copied as required by the email, or can AAK improve the appearance of the valve? He just replied: do your best, the samples are for exhibition. |
