The hydraulic cartridge flow control valve failed in 3 proofs with the old supplier cooperated for 3

The supplier who has cooperated for 3 years has failed to test the hydraulic cartridge flow control valve for 3 times. After AAK took over, the accuracy requirements were met at one time for the sample. The surface roughness of the inner hole of the hydraulic cartridge flow control valve was 0.15, and the cylindricity error was controlled within Φ0.003mm, the operating efficiency of the hydraulic system was also improved from 5% to 10%.

Brand is from Brazil. In March this year, he sent me an inquiry for customized high-precision hydraulic cartridge flow control valve. The surface roughness of the inner hole is Ra0.2, and the cylindricity is Φ 0.003mm. The cylindricity and the surface roughness of the inner hole are the core of the valve hole precision. There are no more than 5 hydraulic cartridge valve manufacturers in Ningbo that can successfully sample at one time.
