50 customized hydraulic cartridge relief valves were completed in 30 days, AAK replaced the original

In March this year, Tancredo, an old customer from Italy, emailed me: Can you complete 50 non-standard customized hydraulic cartridge relief valves in 30 days and the valve hole accuracy within 1μm? In the second half of last year, they developed a high-precision hydraulic pipe pressing machine, which requires the use of hydraulic cartridge relief valves. Due to time constraints, they chose samples from local hydraulic valve manufacturers, but the equipment debugging was not smooth. The pipe pressing accuracy of the hydraulic pipe pressing machine is not up to the standard, because the accuracy of the valve hole of the hydraulic cartridge relief valve exceeds 1.0μm. There is leakage.

Tancredo had to try overseas hydraulic valve manufacturers. The hydraulic cartridge relief valve with 1.0μm hole accuracy is a big challenge for most hydraulic cartridge valve manufacturers.
