AAK Cartridge Valve Manufacturer Care to Customers with Heart

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.

I sent samples and refined 3 selling points.

1. The material of cartridge valve body and valve spool is changed to high-strength alloy steel.

2. The surface treatment of hydraulic cartridge valve is galvanized nickel alloy.

3. The durability of hydraulic cartridge valve ensure for more than 2 million times.

Why should I do this? In fact, it is due to a small matter I met before. I needed to polish 2 stones.
